Detailed Description

Represents a generic declaration context in a program.

A declaration context is data structure that contains declarations (e.g. namespaces).

This class serves as an abstraction for a declaration context inside one of the TypeSystems implemented by the language plugins. It does not have any actual logic in it but only stores an opaque pointer and a pointer to the TypeSystem that gives meaning to this opaque pointer. All methods of this class should call their respective method in the TypeSystem interface and pass the opaque pointer along.

Constructor & Destructor Documentation

◆ CompilerDeclContext() [1/2]

lldb_private::CompilerDeclContext::CompilerDeclContext ( )

default

Constructs an invalid CompilerDeclContext.

◆ CompilerDeclContext() [2/2]

lldb_private::CompilerDeclContext::CompilerDeclContext	(	TypeSystem *	type_system,
		void *	decl_ctx
	)

inline

Constructs a CompilerDeclContext with the given opaque decl context and its respective TypeSystem instance.

This constructor should only be called from the respective TypeSystem implementation.

◆ GetCompilerContext()

std::vector< lldb_private::CompilerContext > CompilerDeclContext::GetCompilerContext ( ) const

Populate a valid compiler context from the current decl context.

Returns: A valid vector of CompilerContext entries that describes this declaration context. The first entry in the vector is the parent of the subsequent entry, so the topmost entry is the global namespace.
