Detailed Description

Represents a class template specialization, which refers to a class template with a given set of template arguments.

Class template specializations represent both explicit specialization of class templates, as in the example below, and implicit instantiations of class templates.

 template<typename T> class array;

 template<>
 class array<bool> { }; // class template specialization array<bool>

void ClassTemplateSpecializationDecl::getNameForDiagnostic	(	raw_ostream &	OS,

getNameForDiagnostic - Appends a human-readable name for this declaration into the given stream.

This is the method invoked by Sema when displaying a NamedDecl in a diagnostic. It does not necessarily produce the same result as printName(); for example, class template specializations are printed with their template arguments.
