Declaration

Description

TemplateTemplateParmDecl - Declares a template template parameter, e.g., "T" in A template template parameter is a TemplateDecl because it defines the name of a template and the template parameters allowable for substitution.

Member Variables

private clang::TemplateTemplateParmDecl::DefArgStorage DefaultArgument

private bool ParameterPack

Whether this parameter is a parameter pack.

private bool ExpandedParameterPack = false

Whether this template template parameter is an "expanded" parameter pack, meaning that it is a pack expansion and we already know the set of template parameters that expansion expands to.

private unsigned int NumExpandedParams = 0

The number of parameters in an expanded parameter pack.

    unsigned int I) const

Description

Retrieve a particular expansion type within an expanded parameter pack.

unsigned int I

¶unsigned int getNumExpansionTemplateParameters()
    const

Description

¶clang::SourceRange getSourceRange() const

Description

¶bool hasDefaultArgument() const

Description

Determine whether this template parameter has a default argument.

Declared at: clang/include/clang/AST/DeclTemplate.h:1745

¶bool isExpandedParameterPack() const

Description

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

Declared at: clang/include/clang/AST/DeclTemplate.h:1725
