175/// Represents a C++ template name within the type system.
176///
177/// A C++ template name refers to a template within the C++ type
178/// system. In most cases, a template name is simply a reference to a
179/// class template, e.g.
180///
181/// \code
182/// template<typename T> class X { };
183///
184/// X<int> xi;
185/// \endcode

187/// Here, the 'X' in \c X<int> is a template name that refers to the
188/// declaration of the class template X, above. Template names can
189/// also refer to function templates, C++0x template aliases, etc.
190///
191/// Some template names are dependent. For example, consider:
192///
193/// \code
194/// template<typename MetaFun, typename T1, typename T2> struct apply2 {
195/// typedef typename MetaFun::template apply<T1, T2>::type type;
196/// };
197/// \endcode
198///
199/// Here, "apply" is treated as a template name within the typename
200/// specifier in the typedef. "apply" is a nested template, and can
201/// only be understood in the context of
203 // NameDecl is either a TemplateDecl or a UsingShadowDecl depending on the
204 // NameKind.
