Create a global module fragment for a C++ module unit.

We model the global module fragment as a submodule of the module interface unit. Unfortunately, we can't create the module interface unit's Module until later, because we don't know what it will be called usually. See C++20 [module.unit]/7.2 for the case we could know its parent.

◆ findAllModulesForHeader()

ArrayRef< ModuleMap::KnownHeader > ModuleMap::findAllModulesForHeader ( const FileEntry * File )

Retrieve all the modules that contain the given header file.

◆ findModuleForHeader()

ModuleMap::KnownHeader ModuleMap::findModuleForHeader	(	const FileEntry *	File,
		bool	AllowTextual = `false`
	)

Retrieve the module that owns the given header file, if any.

Note that this does not implicitly load module maps, except for builtin headers, and does not consult the external source. (Those checks are the responsibility of HeaderSearch.)

Parameters

File	The header file that is likely to be included.
AllowTextual	If `true` and `File` is a textual header, return its owning module. Otherwise, no KnownHeader will be returned if the file is only known as a textual header.

Returns: The module KnownHeader, which provides the module that owns the given header file. The KnownHeader is default constructed to indicate that no module owns this header file.

	)

Find a new module or submodule, or create it if it does not already exist.

Parameters

Name	The name of the module to find or create.
Parent	The module that will act as the parent of this submodule, or nullptr to indicate that this is a top-level module.

Definition at line 681 of file ModuleMap.cpp.

References clang::File, and resolveHeaderDirectives().

◆ finishModuleDeclarationScope()

void clang::ModuleMap::finishModuleDeclarationScope ( )

inline

Creates a new declaration scope for module names, allowing previously defined modules to shadow definitions from the new scope.

Note: Module names from earlier scopes will shadow names from the new scope, which is the opposite of how shadowing works for variables.

Definition at line 586 of file ModuleMap.h.

◆ getAdditionalModuleMapFiles()

AdditionalModMapsSet* clang::ModuleMap::getAdditionalModuleMapFiles ( const Module * M )

inline

Get any module map files other than getModuleMapFileForUniquing(M) that define submodules of a top-level module M.

This is cheaper than getting the module map file for each submodule individually, since the expected number of results is very small.

Definition at line 626 of file ModuleMap.h.

◆ getBuiltinDir()

const DirectoryEntry* clang::ModuleMap::getBuiltinDir ( ) const

inline

Get the directory that contains Clang-supplied include files.

◆ getModuleMapFileForUniquing()

const FileEntry * ModuleMap::getModuleMapFileForUniquing ( const Module * M ) const

Get the module map file that (along with the module name) uniquely identifies this module.

The particular module that Name refers to may depend on how the module was found in header search. However, the combination of Name and this module map will be globally unique for top-level modules. In the case of inferred modules, returns the module map that allowed the inference (e.g. contained 'module *'). Otherwise, returns getContainingModuleMapFile().
