◆ getFunction()

FunctionDecl * clang::FunctionTemplateSpecializationInfo::getFunction ( ) const
inline

Retrieve the declaration of the function template specialization.

◆ getMemberSpecializationInfo()

MemberSpecializationInfo * clang::FunctionTemplateSpecializationInfo::getMemberSpecializationInfo ( ) const
inline

Get the specialization info if this function template specialization is also a member specialization:

template<typename> struct A {
template<typename> void f();
template<> void f<int>();
};

Here, A<int>::f<int> is a function template specialization that is an explicit specialization of A<int>::f, but it's also a member specialization (an implicit instantiation in this case) of A::f<int>. Further:

template<> template<> void A<int>::f<int>() {}

... declares a function template specialization that is an explicit specialization of A<int>::f, and is also an explicit member specialization of A::f<int>.

Note that the TemplateSpecializationKind of the MemberSpecializationInfo need not be the same as that returned by getTemplateSpecializationKind(), and represents the relationship between the function and the class-scope explicit specialization in the original templated class – whereas our TemplateSpecializationKind represents the relationship between the function and the function template, and should always be TSK_ExplicitSpecialization whenever we have MemberSpecializationInfo.
