Detailed description of a construct Although the context model for this element is ANY, detailed descriptions should contain structured DocBook elements that occur within sections, e.g., paragraphs (para, simpara), lists (orderedlist, itemizedlist), tables (informaltable, table), etc. %boost.common.attrib;

Placeholder for an alphabetical list of libraries Developers aren't generally expected to use this element. Its existence is mainly as a placeholder in boost.xml for the alphabetical list of libraries. %boost.common.attrib;

Declares the reference material for a library Reference documentation for a library is contained with a <library-reference> element. The <library-reference> element has no attributes, and contains as children only <header> elements. The <header> element defines a C++ header file. Within each C++ header file lie the definitions of C++ constructs to be documented. The name attribute of the <header> element gives the name of the header, as one would specify when including the header. For instance, the <library-reference> for the Any library may look like this: <library-reference> <header name="boost/any.hpp">  </header> </library-reference> If the Any library contained multiple headers, we would list them all as children of the <library-reference> element. library-reference elements can be nested, so that reference material can be divided into separate sections that each contain different headers. %boost.common.attrib;

Defines a BoostBook book This element is the topmost level defined by boost.xml for all Boost documentation. It will not generally be used by developers. %boost.common.attrib;

Declares a C++ union or union template name CDATA #REQUIRED %boost.common.attrib;

Declares a base class of the enclosing class or struct This element contains the type of the class inherited. access CDATA #IMPLIED pack CDATA #IMPLIED %boost.common.attrib; The access specifier ("public", "private", or "protected") of the inheritance. Set to '1' if this is a pack exapansion.

Declares a variable-length list of template parameters Variable-length template parameter lists are not allowed in C++, but because they are sometimes needed in documentation they are allowed in BoostBook. This element generally expands to "..." and can be used anywhere any other template parameter can be used. %boost.common.attrib;

Defines source code for a test This element will contain the source code for a testcase that will be generated from the documentation. To reduce the amount of escaping in the text, it is recommended to use CDATA sections, which look like this: <![CDATA[ <your program text here: no escaping needed!> ]]> In addition to CDATA sections, code snippets can be pulled in from programlisting elements using the snippet element.

Declares a function BoostBook functions are documented by specifying the function's interface (e.g., its C++ signature) and its behavior. Constructors, destructors, member functions, and free functions all use the same documentation method, although the top-level tags differ. The behavior of functions in BoostBook is documenting using a style similar to that of the C++ standard, with clauses describing the requirements, effects, postconditions, exception behavior, and return values of functions. The following example illustrates some constructors and a destructor for boost::any. Note that one of the constructors takes a single parameter whose name is "other" and whose type, const any& is contained in the <paramtype> element; any number of parameters may be specified in this way. <class name="any"> <constructor> <postconditions><para><this->empty()></para></postconditions> </constructor> <constructor> <parameter name="other"> <paramtype>const <classname>any</classname>&</paramtype> </parameter> <effects> <simpara> Copy constructor that copies content of <code>other</code> into the new instance, so that any content is equivalent in both type and value to the content of <code>other</code>, or empty if <code>other</code> is empty. </simpara> </effects> <throws> <simpara>May fail with a <classname>std::bad_alloc</classname> exception or any exceptions arising from the copy constructor of the contained type. </simpara> </throws> </constructor> <destructor> <effects><simpara>Releases any and all resources used in management of instance.</simpara></effects> <throws><simpara>Nothing.</simpara></throws> </destructor> </class> name CDATA #REQUIRED specifiers CDATA #IMPLIED %boost.common.attrib;

Declares a constructor of the enclosing class General documentation on functions in BoostBook is provided in the function element documentation. specifiers CDATA #IMPLIED %boost.common.attrib;

Declares a namespace BoostBook namespaces are declared via the <namespace> element. As in C++, namespaces can be nested and contain other C++ constructs, such as classes or functions. The name attribute of a <namespace> element gives the namespace name (e.g., "boost"). The Any library is defined entirely within namespace boost by: <library-reference> <header name="boost/any.hpp"> <namespace name="boost">  </namespace> </header> </library-reference> name CDATA #REQUIRED %boost.common.attrib;

What it means when a testcase fails Describes to the user the effect a certain failing testcase will have on the usefulness of a library. This field is useful in cases where a failed testcase does not mean that the library won't be useful, but may mean that certain library features will not be available.

<requirement
  name="includes">foo.hpp</requirement>

One signature of an overloaded function or method A signature refers to one declaration of an overloaded function or method. The signature itself has no name, because the name of the overloaded function or method is used. An overloaded function or method will have several signatures that will generally be typeset together. cv CDATA #IMPLIED specifiers CDATA #IMPLIED %boost.common.attrib;

Declares an access specification for class members The access specifications of class members (public, private, or protected) may be determined by enclosing them in an <access> element. name CDATA #REQUIRED %boost.common.attrib; The name of the access specification, e.g. "public", "private", or "protected".

Declares a class or class template C++ classes and class templates are described via the <class> element. Each class has a name (e.g., "any") given by the name attribute, a purpose given by the <purpose> element, documentation, and a set of types, functions, base classes, and data members. Here is a minimal definition of the boost::any class: <namespace name="boost"> <class name="any"> <purpose> A class whose instances can hold instances of any type that satisfies ValueType requirements. </purpose> </class> </namespace> Additional class documentation can be contained in a description element following the <purpose> element. This documentation will be typeset prior to documentation for specific elements in the class (e.g., constructors or methods). Class inheritance is described via the <inherit> element. The <inherit> element requires an access attribute which must be one of public, protected, or private. The content of the <inherited> element in C++ code that names the class inherited, and may contain markup to link to the class. The following description of the class boost::bad_any_cast describes public inheritance from the class std::bad_cast. It also defines the <purpose> element, which contains a short description of the use of the class. <class name="bad_any_cast"> <inherit access="public"><classname>std::bad_cast</classname></inherit> <purpose><para>The exception thrown in the event of a failed <functionname>any_cast</functionname> of an <classname>any</classname> value.</para></purpose> </class> Class templates are defined by <class> elements with a <template> child element at the beginning. name CDATA #REQUIRED %boost.common.attrib;
