Detailed Description

"lldb/Expression/ClangASTSource.h" Container for all objects relevant to a single name lookup

LLDB needs to create Decls for entities it finds. This class communicates what name is being searched for and provides helper functions to construct Decls given appropriate type information.

Definition at line 26 of file NameSearchContext.h.

Constructor & Destructor Documentation

◆ NameSearchContext()

lldb_private::NameSearchContext::NameSearchContext	(	TypeSystemClang &	clang_ts,
		llvm::SmallVectorImpl< clang::NamedDecl * > &	decls,
		clang::DeclarationName	name,
		const clang::DeclContext *	dc
	)

inline

Constructor.

Initializes class variables.

Parameters

[in]	clang_ts	The TypeSystemClang from which the request originates.
[in]	decls	A reference to a list into which new Decls will be placed. This list is typically empty when the function is called.
[in]	name	The name being searched for (always an Identifier).
[in]	dc	The DeclContext to register Decls in.

Definition at line 63 of file NameSearchContext.h.

Member Function Documentation

◆ AddFunDecl()

clang::NamedDecl * NameSearchContext::AddFunDecl	(	const CompilerType &	type,
		bool	extern_c = `false`
	)

Create a FunDecl with the name being searched for and the provided type and register it in the right places.

Parameters

[in]	type	The opaque QualType for the FunDecl being registered.
[in]	extern_c	If true, build an extern "C" linkage specification for this.
