Detailed Description

TemplateTemplateParmDecl - Declares a template template parameter, e.g., "T" in.

template <template <typename> class T> class container { };

A template template parameter is a TemplateDecl because it defines the name of a template and the template parameters allowable for substitution.

bool clang::TemplateTemplateParmDecl::hasDefaultArgument ( ) const
inline
bool clang::TemplateTemplateParmDecl::isExpandedParameterPack ( ) const
inline

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

A parameter pack is an expanded parameter pack when the original parameter pack's template parameter list was itself a pack expansion, and that expansion has already been expanded. For exampe, given:

template<typename...Types> struct Outer {
template<template<Types> class...Templates> struct Inner;
};

The parameter pack Templates is a pack expansion, which expands the pack Types. When Types is supplied with template arguments by instantiating Outer, the instantiation of Templates is an expanded parameter pack.

bool clang::TemplateTemplateParmDecl::isPackExpansion ( ) const

A template template parameter pack is a pack expansion if its template parameter list contains an unexpanded parameter pack.
