Member Function Documentation

◆ addDecl()

void DeclContext::addDecl ( Decl * D )

Add the declaration D into this context.

This routine should be invoked when the declaration D has first been declared, to place D into the context where it was (lexically) defined. Every declaration must be added to one (and only one!) context, where it can be visited via [decls_begin(), decls_end()). Once a declaration has been added to its lexical context, the corresponding DeclContext owns the declaration.

If D is also a NamedDecl, it will be made visible within its semantic context via makeDeclVisibleInContext.

◆ addDeclInternal()

void DeclContext::addDeclInternal ( Decl * D )

Add the declaration D into this context, but suppress searches for external declarations with the same name.

Although analogous in function to addDecl, this removes an important check. This is only useful if the Decl is being added in response to an external search; in all other cases, addDecl() is the right function to use. See the ASTImporter for use cases.

◆ addHiddenDecl()

void DeclContext::addHiddenDecl ( Decl * D )

Add the declaration D to this context without modifying any lookup tables.

This is useful for some operations in dependent contexts where the semantic context might not be dependent; this basically only happens with friends.

◆ collectAllContexts()

void DeclContext::collectAllContexts ( SmallVectorImpl< DeclContext *> & Contexts )

Collects all of the declaration contexts that are semantically connected to this declaration context.

For declaration contexts that have multiple semantically connected but syntactically distinct contexts, such as C++ namespaces, this routine retrieves the complete set of such declaration contexts in source order. For example, given:

namespace N {
  int x;
}
namespace N {
  int y;
}

The Contexts parameter will contain both definitions of N.

Parameters

Contexts Will be cleared and set to the set of declaration contexts that are semanticaly connected to this declaration context, in source order, including this context (which may be the only result, for non-namespace contexts).

◆ isTransparentContext()

bool DeclContext::isTransparentContext ( ) const

isTransparentContext - Determines whether this context is a "transparent" context, meaning that the members declared in this context are semantically declared in the nearest enclosing non-transparent (opaque) context but are lexically declared in this context.

For example, consider the enumerators of an enumeration type:

enum E {
  Val1
};

Here, E is a transparent context, so its enumerator (Val1) will appear (semantically) that it is in the same context of E. Examples of transparent contexts include: enumerations (except for C++0x scoped enums), and C++ linkage specifications.

◆ localUncachedLookup()

void DeclContext::localUncachedLookup	(	DeclarationName	Name,
		SmallVectorImpl< NamedDecl *> &	Results
	)

A simplistic name lookup mechanism that performs name lookup into this declaration context without consulting the external source.

This function should almost never be used, because it subverts the usual relationship between a DeclContext and the external source. See the ASTImporter for the (few, but important) use cases.

FIXME: This is very inefficient; replace uses of it with uses of noload_lookup.

Definition at line 1632 of file DeclBase.cpp.

◆ lookup()

DeclContext::lookup_result DeclContext::lookup ( DeclarationName Name ) const

lookup - Find the declarations (if any) with the given Name in this context.

Returns a range of iterators that contains all of the declarations with this name, with object, function, member, and enumerator names preceding any tag name. Note that this routine will not look into parent contexts.

◆ makeDeclVisibleInContext()

void DeclContext::makeDeclVisibleInContext ( NamedDecl * D )

Makes a declaration visible within this context.

This routine makes the declaration D visible to name lookup within this context and, if this is a transparent context, within its parent contexts up to the first enclosing non-transparent context. Making a declaration visible within a context does not transfer ownership of a declaration, and a declaration can be visible in many contexts that aren't its lexical context.

If D is a redeclaration of an existing declaration that is visible from this context, as determined by NamedDecl::declarationReplaces, the previous declaration will be replaced with D.
