◆ isExpandedParameterPack()

bool clang::TemplateTypeParmDecl::isExpandedParameterPack ( ) const
inline

Whether this parameter is a template type parameter pack that has a known list of different type-constraints at different positions.

A parameter pack is an expanded parameter pack when the original parameter pack's type-constraint was itself a pack expansion, and that expansion has already been expanded. For example, given:

template<typename ...Types>
struct X {
template<convertible_to<Types> ...Convertibles>
struct Y { /* ... */ };
};
#define X(type, name)
Definition: Value.h:142

The parameter pack Convertibles has (convertible_to<Types> && ...) as its type-constraint. When Types is supplied with template arguments by instantiating X, the instantiation of Convertibles becomes an expanded parameter pack. For example, instantiating X<int, unsigned int> results in Convertibles being an expanded parameter pack of size 2 (use getNumExpansionTypes() to get this number).

◆ isPackExpansion()
