Member Typedef Documentation

typedef const TemplateArgument* clang::TemplateArgument::pack_iterator

Iterator that traverses the elements of a template argument pack.

Member Enumeration Documentation

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). Also used to represent a non-dependent __uuidof expression (a Microsoft extension).
Pack	The template argument is actually a parameter pack. Arguments are stored in the Args struct.

clang::TemplateArgument::TemplateArgument

(

TemplateName

Name

)

[inline]

Construct a template argument that is a template.

This form of template argument is generally used for template template parameters. However, the template name could be a dependent template name that ends up being instantiated to a function template whose address is taken.

Parameters:

Name	The template name.

clang::TemplateArgument::TemplateArgument	(	TemplateName	Name,

Construct a template argument that is a template pack expansion.

This form of template argument is generally used for template template parameters. However, the template name could be a dependent template name that ends up being instantiated to a function template whose address is taken.

)

[inline]

This form of template argument only occurs in template argument lists used for dependent types and for expression; it will not occur in a non-dependent, canonical template argument list.
