There should be no functional changes at all, but if there's any issue,
please let me know.

It also counts +as the successor of the GNU Library Public License, version 2, hence the +version number 2.1.] + +@sp 1 +@center Preamble +@sp 1 + +The licenses for most software are designed to take away your freedom to +share and change it. By contrast, the GNU General Public Licenses are +intended to guarantee your freedom to share and change free software--to +make sure the software is free for all its users. + +This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the Free +Software Foundation and other authors who decide to use it. You can use +it too, but we suggest you first think carefully about whether this +license or the ordinary General Public License is the better strategy to +use in any particular case, based on the explanations below. + +When we speak of free software, we are referring to freedom of use, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish); that you receive source code or can get it if +you want it; that you can change the software and use pieces of it in +new free programs; and that you are informed that you can do these +things. + +To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + +For example, if you distribute copies of the library, whether gratis or +for a fee, you must give the recipients all the rights that we gave you. +You must make sure that they, too, receive or can get the source code. +If you link other code with the library, you must provide complete +object files to the recipients, so that they can relink them with the +library after making changes to the library and recompiling it. And you +must show them these terms so they know their rights. + +We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + +To protect each distributor, we want to make it very clear that there is +no warranty for the free library. Also, if the library is modified by +someone else and passed on, the recipients should know that what they +have is not the original version, so that the original author's +reputation will not be affected by problems that might be introduced by +others. + +Finally, software patents pose a constant threat to the existence of any +free program. We wish to make sure that a company cannot effectively +restrict the users of a free program by obtaining a restrictive license +from a patent holder. Therefore, we insist that any patent license +obtained for a version of the library must be consistent with the full +freedom of use specified in this license. + +Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License. This license, the GNU Lesser General Public +License, applies to certain designated libraries, and is quite different +from the ordinary General Public License. We use this license for +certain libraries in order to permit linking those libraries into +non-free programs. + +When a program is linked with a library, whether statically or using a +shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the entire +combination fits its criteria of freedom. The Lesser General Public +License permits more lax criteria for linking other code with the +library. + +We call this license the ``Lesser'' General Public License because it does +Less to protect the user's freedom than the ordinary General Public +License. It also provides other free software developers Less of an +advantage over competing non-free programs. These disadvantages are the +reason we use the ordinary General Public License for many libraries. +However, the Lesser license provides advantages in certain special +circumstances. + +For example, on rare occasions, there may be a special need to encourage +the widest possible use of a certain library, so that it becomes a +de-facto standard. To achieve this, non-free programs must be allowed +to use the library. A more frequent case is that a free library does +the same job as widely used non-free libraries. In this case, there is +little to gain by limiting the free library to free software only, so we +use the Lesser General Public License. + +In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of free +software. For example, permission to use the GNU C Library in non-free +programs enables many more people to use the whole GNU operating system, +as well as its variant, the GNU/Linux operating system. + +Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is linked +with the Library has the freedom and the wherewithal to run that program +using a modified version of the Library. + +The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +``work based on the library'' and a ``work that uses the library''. The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + +@page + +@center GNU LESSER GENERAL PUBLIC LICENSE +@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + +@enumerate 0 + +@sp 1 +@item +This License Agreement applies to any software library or other program +which contains a notice placed by the copyright holder or other +authorized party saying it may be distributed under the terms of this +Lesser General Public License (also called ``this License''). Each +licensee is addressed as ``you''. + +A ``library'' means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + +The ``Library'', below, refers to any such software library or work which +has been distributed under these terms. A ``work based on the Library'' +means either the Library or any derivative work under copyright law: +that is to say, a work containing the Library or a portion of it, either +verbatim or with modifications and/or translated straightforwardly into +another language. (Hereinafter, translation is included without +limitation in the term ``modification''.) + +``Source code'' for a work means the preferred form of the work for making +modifications to it. For a library, complete source code means all the +source code for all modules it contains, plus any associated interface +definition files, plus the scripts used to control compilation and +installation of the library. + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of running +a program using the Library is not restricted, and output from such a +program is covered only if its contents constitute a work based on the +Library (independent of the use of the Library in a tool for writing +it). Whether that is true depends on what the Library does and what the +program that uses the Library does. + +@sp 1 +@item +You may copy and distribute verbatim copies of the Library's complete +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the notices +that refer to this License and to the absence of any warranty; and +distribute a copy of this License along with the Library. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + +@sp 1 +@item +You may modify your copy or copies of the Library or any portion of it, +thus forming a work based on the Library, and copy and distribute such +modifications or work under the terms of Section 1 above, provided that +you also meet all of these conditions: + +@enumerate a + +@item +The modified work must itself be a software library. + +@sp 1 +@item +You must cause the files modified to carry prominent notices stating +that you changed the files and the date of any change. + +@sp 1 +@item +You must cause the whole of the work to be licensed at no charge to all +third parties under the terms of this License. + +@sp 1 +@item +If a facility in the modified Library refers to a function or a table of +data to be supplied by an application program that uses the facility, +other than as an argument passed when the facility is invoked, then you +must make a good faith effort to ensure that, in the event an +application does not supply such function or table, the facility still +operates, and performs whatever part of its purpose remains meaningful. + +(For example, a function in a library to compute square roots has a +purpose that is entirely well-defined independent of the application. +Therefore, Subsection 2d requires that any application-supplied function +or table used by this function must be optional: if the application does +not supply it, the square root function must still compute square +roots.) + +@end enumerate + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, and +can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based on +the Library, the distribution of the whole must be on the terms of this +License, whose permissions for other licensees extend to the entire +whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of a +storage or distribution medium does not bring the other work under the +scope of this License. + +@sp 1 +@item +You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so that +they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + +Once this change is made in a given copy, it is irreversible for that +copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + +This option is useful when you wish to copy part of the code of the +Library into a program that is not a library. + +@sp 1 +@item +You may copy and distribute the Library (or a portion or derivative of +it, under Section 2) in object code or executable form under the terms +of Sections 1 and 2 above provided that you accompany it with the +complete corresponding machine-readable source code, which must be +distributed under the terms of Sections 1 and 2 above on a medium +customarily used for software interchange. + +If distribution of object code is made by offering access to copy from a +designated place, then offering equivalent access to copy the source +code from the same place satisfies the requirement to distribute the +source code, even though third parties are not compelled to copy the +source along with the object code. + +@sp 1 +@item +A program that contains no derivative of any portion of the Library, but +is designed to work with the Library by being compiled or linked with +it, is called a ``work that uses the Library''. Such a work, in +isolation, is not a derivative work of the Library, and therefore falls +outside the scope of this License. + +However, linking a ``work that uses the Library'' with the Library creates +an executable that is a derivative of the Library (because it contains +portions of the Library), rather than a ``work that uses the library''. +The executable is therefore covered by this License. Section 6 states +terms for distribution of such executables. + +When a ``work that uses the Library'' uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be linked +without the Library, or if the work is itself a library. The threshold +for this to be true is not precisely defined by law. + +If such an object file uses only numerical parameters, data structure +layouts and accessors, and small macros and small inline functions (ten +lines or less in length), then the use of the object file is +unrestricted, regardless of whether it is legally a derivative work. +(Executables containing this object code plus portions of the Library +will still fall under Section 6.) + +Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, whether +or not they are linked directly with the Library itself. + +@sp 1 +@item +As an exception to the Sections above, you may also combine or link a +``work that uses the Library'' with the Library to produce a work +containing portions of the Library, and distribute that work under terms +of your choice, provided that the terms permit modification of the work +for the customer's own use and reverse engineering for debugging such +modifications. + +You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + +@enumerate a + +@sp 1 +@item +Accompany the work with the complete corresponding machine-readable +source code for the Library including whatever changes were used in the +work (which must be distributed under Sections 1 and 2 above); and, if +the work is an executable linked with the Library, with the complete +machine-readable ``work that uses the Library'', as object code and/or +source code, so that the user can modify the Library and then relink to +produce a modified executable containing the modified Library. (It is +understood that the user who changes the contents of definitions files +in the Library will not necessarily be able to recompile the application +to use the modified definitions.) + +@sp 1 +@item +Use a suitable shared library mechanism for linking with the Library. A +suitable mechanism is one that (1) uses at run time a copy of the +library already present on the user's computer system, rather than +copying library functions into the executable, and (2) will operate +properly with a modified version of the library, if the user installs +one, as long as the modified version is interface-compatible with the +version that the work was made with. + +@sp 1 +@item +Accompany the work with a written offer, valid for at least three years, +to give the same user the materials specified in Subsection 6a, above, +for a charge no more than the cost of performing this distribution. + +@sp 1 +@item +If distribution of the work is made by offering access to copy from a +designated place, offer equivalent access to copy the above specified +materials from the same place. + +@sp 1 +@item +Verify that the user has already received a copy of these materials or +that you have already sent this user a copy. + +@end enumerate + +For an executable, the required form of the ``work that uses the Library'' +must include any data and utility programs needed for reproducing the +executable from it. However, as a special exception, the materials to +be distributed need not include anything that is normally distributed +(in either source or binary form) with the major components (compiler, +kernel, and so on) of the operating system on which the executable runs, +unless that component itself accompanies the executable. + +It may happen that this requirement contradicts the license restrictions +of other proprietary libraries that do not normally accompany the +operating system. Such a contradiction means you cannot use both them +and the Library together in an executable that you distribute. + +@sp 1 +@item +You may place library facilities that are a work based on the Library +side-by-side in a single library together with other library facilities +not covered by this License, and distribute such a combined library, +provided that the separate distribution of the work based on the Library +and of the other library facilities is otherwise permitted, and provided +that you do these two things: + +@enumerate a + +@sp 1 +@item +Accompany the combined library with a copy of the same work based on the +Library, uncombined with any other library facilities. This must be +distributed under the terms of the Sections above. + +@sp 1 +@item +Give prominent notice with the combined library of the fact that part of +it is a work based on the Library, and explaining where to find the +accompanying uncombined form of the same work. + +@end enumerate + +@sp 1 +@item +You may not copy, modify, sublicense, link with, or distribute the +Library except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense, link with, or distribute the +Library is void, and will automatically terminate your rights under this +License. However, parties who have received copies, or rights, from you +under this License will not have their licenses terminated so long as +such parties remain in full compliance. + +@sp 1 +@item +You are not required to accept this License, since you have not signed +it. However, nothing else grants you permission to modify or distribute +the Library or its derivative works. These actions are prohibited by +law if you do not accept this License. Therefore, by modifying or +distributing the Library (or any work based on the Library), you +indicate your acceptance of this License to do so, and all its terms and +conditions for copying, distributing or modifying the Library or works +based on it. + +@sp 1 +@item +Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + +@sp 1 +@item +If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent license +would not permit royalty-free redistribution of the Library by all those +who receive copies directly or indirectly through you, then the only way +you could satisfy both it and this License would be to refrain entirely +from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply, and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is implemented +by public license practices. Many people have made generous +contributions to the wide range of software distributed through that +system in reliance on consistent application of that system; it is up to +the author/donor to decide if he or she is willing to distribute +software through any other system and a licensee cannot impose that +choice. + +This section is intended to make thoroughly clear what is believed to be +a consequence of the rest of this License. + +@sp 1 +@item +If the distribution and/or use of the Library is restricted in certain +countries either by patents or by copyrighted interfaces, the original +copyright holder who places the Library under this License may add an +explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + +@sp 1 +@item +The Free Software Foundation may publish revised and/or new versions of +the Lesser General Public License from time to time. Such new versions +will be similar in spirit to the present version, but may differ in +detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and ``any +later version'', you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a license +version number, you may choose any version ever published by the Free +Software Foundation. + +@sp 1 +@item +If you wish to incorporate parts of the Library into other free programs +whose distribution conditions are incompatible with these, write to the +author to ask for permission. For software which is copyrighted by the +Free Software Foundation, write to the Free Software Foundation; we +sometimes make exceptions for this.

The library features a fully +reentrant parser and includes bindings for both the C and C++ +programming languages. + +The library runs on modern POSIX-compilant systems, such as Linux, +Solaris, and Mac OS X (Darwin), as well as on Microsoft Windows +2000/XP and later (with either Microsoft Visual Studio 2005 or later, +or the GNU toolchain via the MinGW environment). + +@node Why Another Configuration File Library?, Using the Library from a C Program, , Introduction +@comment node-name, next, previous, up +@section Why Another Configuration File Library? + +There are several open-source configuration file libraries available +as of this writing. This library was written because each of those +libraries falls short in one or more ways. The main features of +@i{libconfig} that set it apart from the other libraries are: + +@itemize @bullet + +@item A fully reentrant parser. Independent configurations can be parsed in concurrent threads at the same time. + +@item Both C @i{and} C++ bindings, as well as hooks to allow for the creation of wrappers in other languages. + +@item A simple, structured configuration file format that is more +readable and compact than XML and more flexible than the obsolete but +prevalent Windows ``INI'' file format. + +@item A low-footprint implementation (just 37K for the C library and 76K for +the C++ library) that is suitable for memory-constrained systems. + +@item Proper documentation. + +@end itemize + +@node Using the Library from a C Program, Using the Library from a C++ Program, Why Another Configuration File Library?, Introduction +@comment node-name, next, previous, up +@section Using the Library from a C Program + +To use the library from C code, include the following preprocessor +directive in your source files: + +@sp 1 +@smallexample +#include <libconfig.h> +@end smallexample +@sp 1 + +To link with the library, specify @samp{-lconfig} as an argument to the +linker. + +@node Using the Library from a C++ Program, Multithreading Issues, Using the Library from a C Program, Introduction +@comment node-name, next, previous, up +@section Using the Library from a C++ Program + +To use the library from C++, include the following preprocessor +directive in your source files: + +@sp 1 +@smallexample +#include <libconfig.h++> +@end smallexample +@sp 1 + +Or, alternatively: + +@sp 1 +@smallexample +#include <libconfig.hh> +@end smallexample +@sp 1 +@page +The C++ API classes are defined in the namespace @samp{libconfig}, hence the +following statement may optionally be used: + +@sp 1 +@smallexample +using namespace libconfig; +@end smallexample +@sp 1 + +To link with the library, specify @samp{-lconfig++} as an argument to +the linker. + +@node Multithreading Issues, Internationalization Issues, Using the Library from a C++ Program, Introduction +@comment node-name, next, previous, up +@section Multithreading Issues + +@i{Libconfig} is fully @dfn{reentrant}; the functions in the library +do not make use of global variables and do not maintain state between +successive calls. Therefore two independent configurations may be safely +manipulated concurrently by two distinct threads. + +@i{Libconfig} is not @dfn{thread-safe}. The library is not aware of +the presence of threads and knows nothing about the host system's +threading model. Therefore, if an instance of a configuration is to be +accessed from multiple threads, it must be suitably protected by +synchronization mechanisms like read-write locks or mutexes; the +standard rules for safe multithreaded access to shared data must be +observed. + +@i{Libconfig} is not @dfn{async-safe}. Calls should not be made into +the library from signal handlers, because some of the C library +routines that it uses may not be async-safe. + +@i{Libconfig} is not guaranteed to be @dfn{cancel-safe}. Since it is +not aware of the host system's threading model, the library does not +contain any thread cancellation points. In most cases this will not be +an issue for multithreaded programs. However, be aware that some of +the routines in the library (namely those that read/write +configurations from/to files or streams) perform I/O using C library +routines which may potentially block; whether or not these C library +routines are cancel-safe depends on the host system. + +@node Internationalization Issues, Compiling Using pkg-config, Multithreading Issues, Introduction +@comment node-name, next, previous, up +@section Internationalization Issues + +@cindex Unicode +@cindex UTF-8 +@i{Libconfig} does not natively support Unicode configuration files, +but string values may contain Unicode text encoded in UTF-8; such +strings will be treated as ordinary 8-bit ASCII text by the +library. It is the responsibility of the calling program to perform +the necessary conversions to/from wide (@t{wchar_t}) strings using the +wide string conversion functions such as @t{mbsrtowcs()} and +@t{wcsrtombs()} or the @t{iconv()} function of the @i{libiconv} +library. + +@cindex locale +The textual representation of a floating point value varies by +locale. However, the @i{libconfig} grammar specifies that +floating point values are represented using a period (`.') as the +radix symbol; this is consistent with the grammar of most programming +languages. When a configuration is read in or written out, +@i{libconfig} temporarily changes the @t{LC_NUMERIC} category of the +locale of the calling thread to the ``C'' locale to ensure consistent +handling of floating point values regardless of the locale(s) in use +by the calling program. + +Note that the MinGW environment does not (as of this writing) provide +functions for changing the locale of the calling thread. Therefore, +when using @i{libconfig} in that environment, the calling program is +responsible for changing the @t{LC_NUMERIC} category of the locale to +the "C" locale before reading or writing a configuration. + +@node Compiling Using pkg-config, Version Test Macros, Internationalization Issues, Introduction +@comment node-name, next, previous, up +@section Compiling Using pkg-config + +On UNIX systems you can use the @i{pkg-config} utility (version 0.20 +or later) to automatically select the appropriate compiler and linker +switches for @i{libconfig}.

The path is a dot-separated sequence of names, beginning +at a top-level group and ending at the setting itself. Each name in +the path is the name of a setting; if the setting has no name because +it is an element in a list or array, an integer index in square +brackets can be used as the name. + +For example, in our hypothetical configuration file, the path to the +@code{x} setting is @code{application.window.pos.x}; the path to the +@code{version} setting is simply @code{version}; and the path to the +@code{title} setting of the second book in the @code{books} list is +@code{application.books.[1].title}. + +The datatype of a value is determined from the format of the value +itself. If the value is enclosed in double quotes, it is treated as a +string. If it looks like an integer or floating point number, it is +treated as such. If it is one of the values @code{TRUE}, @code{true}, +@code{FALSE}, or @code{false} (or any other mixed-case version of +those tokens, e.g., @code{True} or @code{FaLsE}), it is treated as a +boolean. If it consists of a comma-separated list of values enclosed +in square brackets, it is treated as an array. And if it consists of a +comma-separated list of values enclosed in parentheses, it is treated +as a list. Any value which does not meet any of these criteria is +considered invalid and results in a parse error. + +All names are case-sensitive. They may consist only of alphanumeric +characters, dashes (@samp{-}), underscores (@samp{_}), and asterisks +(@samp{*}), and must begin with a letter or asterisk. No other +characters are allowed. + +In C and C++, integer, 64-bit integer, floating point, and string +values are mapped to the types @code{int}, @code{long long}, +@code{double}, and @code{const char *}, respectively.

(To understand why, see section 11.4.1 of @i{The C++ +Programming Language}.) + +The solution to this problem is to use an explicit conversion that +avoids the construction of an intermediate @code{std::string} object, +as follows: + +@cartouche +@smallexample +std::string title; +. +. +. +title = (const char *)config.lookup("application.window.title"); +@end smallexample +@end cartouche + +Or, alternatively, use the @code{c_str()} method, which has the same effect: + +@cartouche +@smallexample +std::string title; +. +. +. +title = config.lookup("application.window.title").c_str(); +@end smallexample +@end cartouche + +If the assignment is invalid due to a type mismatch, a +@code{SettingTypeException} is thrown. + +@end deftypemethod + +@deftypemethod Setting {Setting &} operator= (@w{bool @var{value}}) +@deftypemethodx Setting {Setting &} operator= (@w{int @var{value}}) +@deftypemethodx Setting {Setting &} operator= (@w{long @var{value}}) +@deftypemethodx Setting {Setting &} operator= (@w{const long long &@var{value}}) +@deftypemethodx Setting {Setting &} operator= (@w{float @var{value}}) +@deftypemethodx Setting {Setting &} operator= (@w{const double &@var{value}}) +@deftypemethodx Setting {Setting &} operator= (@w{const char *@var{value}}) +@deftypemethodx Setting {Setting &} operator= (@w{const std::string &@var{value}}) + +These assignment operators allow values of type @i{bool}, @i{int}, +@i{long}, @i{long long}, @i{float}, @i{double}, @i{const char *}, and +@i{std::string} to be assigned to a setting.

The following +example presents a concise way to look up three values at once and +perform error handling if any of them are not found or are of the +wrong type: + +@sp 1 +@cartouche +@smallexample +int var1; +double var2; +const char *var3; + +if(setting.lookupValue("var1", var1) + && setting.lookupValue("var2", var2) + && setting.lookupValue("var3", var3)) +@{ + // use var1, var2, var3 +@} +else +@{ + // error handling here +@} +@end smallexample +@end cartouche + +This approach also takes advantage of the short-circuit evaluation +rules of C++, e.g., if the first lookup fails (returning @code{false}), the +remaining lookups are skipped entirely. + +@end deftypemethod + +@deftypemethod Setting {Setting &} add (@w{const std::string &@var{name}}, @w{Setting::Type @var{type}}) +@deftypemethodx Setting {Setting &} add (@w{const char *@var{name}}, @w{Setting::Type @var{type}}) + +These methods add a new child setting with the given @var{name} and +@var{type} to the setting, which must be a group.

If @var{type} is a +scalar type, the new setting will have a default value of 0, 0.0, +@code{false}, or @code{NULL}, as appropriate. + +The method throws a @code{SettingTypeException} if the setting is not +an array or list, or if @var{type} is invalid. + +@end deftypemethod + +@deftypemethod Setting void remove (@w{const std::string &@var{name}}) +@deftypemethodx Setting void remove (@w{const char *@var{name}}) + +These methods remove the child setting with the given @var{name} from +the setting, which must be a group.
