VarDecl * First

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 constexpr T pi = T(3.1415926535897932385);

template<>

constexpr float pi;

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.
