Represents a C++ nested name specifier, such as "\::std::vector::".

C++ nested name specifiers are the prefixes to qualified names. For example, "foo::" in "foo::x" is a nested name specifier. Nested name specifiers are made up of a sequence of specifiers, each of which can be a namespace, type, identifier (for dependent names), decltype specifier, or the global specifier ('::'). The last two specifiers can only appear at the start of a nested-namespace-specifier.

◆ SpecifierKind

The kind of specifier that completes this nested name specifier.

Enumerator
Identifier An identifier, stored as an IdentifierInfo*.
Namespace A namespace, stored as a NamespaceDecl*.
NamespaceAlias A namespace alias, stored as a NamespaceAliasDecl*.
TypeSpec A type, stored as a Type*.
TypeSpecWithTemplate A type that was preceded by the 'template' keyword, stored as a Type*.
Global The global specifier '::'. There is no stored value.
Super Microsoft's '__super' specifier, stored as a CXXRecordDecl* of the class it appeared in.

◆ Create() [1/5]

Builds a specifier that consists of just an identifier.

The nested-name-specifier is assumed to be dependent, but has no prefix because the prefix is implied by something outside of the nested name specifier, e.g., in "x->Base::f", the "x" has a dependent type.

Definition at line 113 of file NestedNameSpecifier.cpp.

◆ Create() [2/5]

◆ Create() [3/5]

Builds a specifier combining a prefix and an identifier.

The prefix must be dependent, since nested name specifiers referencing an identifier are only permitted when the identifier cannot be resolved.
