class VarTemplateSpecializationDecl

Declaration

class VarTemplateSpecializationDecl : public VarDecl, public Node { /* full declaration omitted */ };

Description

Represents a variable template specialization, which refers to a variable template with a given set of template arguments. Variable template specializations represent both explicit specializations of variable templates, as in the example below, and implicit instantiations of variable templates.

Member Variables

private llvm::PointerUnion< VarTemplateDecl*, SpecializedPartialSpecialization*> SpecializedTemplate

The template that this specialization specializes.

private clang::VarTemplateSpecializationDecl:: ExplicitSpecializationInfo* ExplicitInfo = nullptr

Further info for explicit template specialization/instantiation. Does not apply to implicit specializations.

private const clang::TemplateArgumentList* TemplateArgs

The template arguments used to describe this specialization.

private const clang::ASTTemplateArgumentListInfo* TemplateArgsInfo = nullptr

private clang::SourceLocation PointOfInstantiation

The point where this template was instantiated (if any).

private unsigned int SpecializationKind

The kind of specialization this declaration refers to. Really a value of type TemplateSpecializationKind.

private unsigned int IsCompleteDefinition

Whether this declaration is a complete definition of the variable template specialization. We can't otherwise tell apart an instantiated declaration from an instantiated definition with no initializer.

¶clang::SourceLocation getExternLoc() const

Description

Gets the location of the extern keyword, if present.

Declared at: clang/include/clang/AST/DeclTemplate.h:2909

¶llvm::PointerUnion<
    VarTemplateDecl*,
    VarTemplatePartialSpecializationDecl*>
getInstantiatedFrom() const

Description

If this variable template specialization is an instantiation of a template (rather than an explicit specialization), return the variable template or variable template partial specialization from which it was instantiated.

Declared at: clang/include/clang/AST/DeclTemplate.h:2835

¶clang::VarTemplateSpecializationDecl*
getMostRecentDecl()

Declared at: clang/include/clang/AST/DeclTemplate.h:2771

¶void getNameForDiagnostic(
    llvm::raw_ostream& OS,
    const clang::PrintingPolicy& Policy,
    bool Qualified) const

Description

Appends a human-readable name for this declaration into the given stream. This is the method invoked by Sema when displaying a NamedDecl in a diagnostic. It does not necessarily produce the same result as printName(); for example, class template specializations are printed with their template arguments.

Declared at: clang/include/clang/AST/DeclTemplate.h:2768

Parameters

llvm::raw_ostream& OS

const clang::PrintingPolicy& Policy

bool Qualified

¶clang::SourceLocation getPointOfInstantiation()
    const

Description

Get the point of instantiation (if any), or null if none.

Declared at: clang/include/clang/AST/DeclTemplate.h:2819

¶clang::TemplateSpecializationKind
getSpecializationKind() const

Description

Determine the kind of specialization that this declaration represents.

Declared at: clang/include/clang/AST/DeclTemplate.h:2793

¶clang::VarTemplateDecl* getSpecializedTemplate()
    const

Declared at: clang/include/clang/AST/DeclTemplate.h:2777

¶llvm::PointerUnion<
    VarTemplateDecl*,
    VarTemplatePartialSpecializationDecl*>
getSpecializedTemplateOrPartial() const

Description

Retrieve the variable template or variable template partial specialization which was specialized by this.

Declared at: clang/include/clang/AST/DeclTemplate.h:2846

¶const clang::TemplateArgumentList&

Description

Retrieve the template arguments of the variable template specialization.

Declared at: clang/include/clang/AST/DeclTemplate.h:2865

Returns

For a variable template specialization instantiated from the primary template, this function will return the same template arguments as getTemplateArgs(). For a variable template specialization instantiated from a variable template partial specialization, this function will the return deduced template arguments for the variable template partial specialization itself.
