Member Typedef Documentation

pack_iterator

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

Iterator that traverses the elements of a template argument pack.

Definition at line 336 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). 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.

TemplateArgument() [4/10]

TemplateArgument::TemplateArgument	(	ASTContext &	Ctx,

Definition at line 166 of file TemplateBase.h.

References clang::QualType::getAsOpaquePtr(), Integer, and Integer.

TemplateArgument() [6/10]

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.

Definition at line 179 of file TemplateBase.h.

TemplateArgument() [7/10]

clang::TemplateArgument::TemplateArgument ( TemplateName  Name, Optional< unsigned >  NumExpansions  )

inline

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.

Parameters

Name	The template name.
NumExpansions	The number of expansions that will be generated by instantiating

Definition at line 196 of file TemplateBase.h.

TemplateArgument() [8/10]

clang::TemplateArgument::TemplateArgument ( Expr *  E )

inline

Construct a template argument that is an expression.

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.

Definition at line 210 of file TemplateBase.h.

TemplateArgument() [9/10]

clang::TemplateArgument::TemplateArgument ( ArrayRef< TemplateArgument >  Args )

inlineexplicit

Construct a template argument that is a template argument pack.

We assume that storage for the template arguments provided outlives the TemplateArgument itself.
