Detailed Description

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

Variable template specializations represent both explicit specializations of variable templates, as in the example below, and implicit instantiations of variable templates.

template<typename T> constexpr T pi = T(3.1415926535897932385);
template<>
constexpr float pi<float>; // variable template specialization pi<float>

◆ getNameForDiagnostic()

void VarTemplateSpecializationDecl::getNameForDiagnostic ( raw_ostream &  OS,

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.

Reimplemented from clang::NamedDecl.

const TemplateArgumentList& clang::VarTemplateSpecializationDecl::getTemplateInstantiationArgs ( ) const
inline

Retrieve the set of template arguments that should be used to instantiate the initializer of the variable template or variable template partial specialization from which this variable template specialization was instantiated.

Returns
For a variable template specialization instantiated from the primary template, this function will return the same template arguments as getTemplateArgs(). For a variable template specialization instantiated from a variable template partial specialization, this function will the return deduced template arguments for the variable template partial specialization itself.
