◆ pack_iterator

using clang::TemplateArgument::pack_iterator = const TemplateArgument *

Iterator that traverses the elements of a template argument pack.

Definition at line 348 of file TemplateBase.h.

Member Enumeration Documentation

◆ ArgKind

enum clang::TemplateArgument::ArgKind

The kind of template argument we're storing.

Enumerator
Null	Represents an empty template argument, e.g., one that has not been deduced.
Type	The template argument is a type.
Declaration	The template argument is a declaration that was provided for a pointer, reference, or pointer to member non-type template parameter.
NullPtr	The template argument is a null pointer or null pointer to member that was provided for a non-type template parameter.
Integral	The template argument is an integral value stored in an llvm::APSInt that was provided for an integral non-type template parameter.
Template	The template argument is a template name that was provided for a template template parameter.
TemplateExpansion	The template argument is a pack expansion of a template name that was provided for a template template parameter.
Expression	The template argument is an expression, and we've not resolved it to one of the other forms yet, either because it's dependent or because we're representing a non-canonical template argument (for instance, in a TemplateSpecializationType).
Pack	The template argument is actually a parameter pack. Arguments are stored in the Args struct.
