ConflictCallback

using clang::VisibleModuleSet::ConflictCallback = llvm::function_ref<void(ArrayRef<Module *> Path, Module *Conflict, StringRef Message)>

A callback to call when a module conflict is found.

Path consists of a sequence of modules from the conflicting module to the one made visible, where each was exported by the next.

VisibleCallback

using clang::VisibleModuleSet::VisibleCallback = llvm::function_ref<void(Module *M)>

A callback to call when a module is made visible (directly or indirectly) by a call to setVisible.

Member Function Documentation

getGeneration()

unsigned clang::VisibleModuleSet::getGeneration ( ) const

inline

Get the current visibility generation.

Incremented each time the set of visible modules changes in any way.

Definition at line 858 of file Module.h.

getImportLoc()

SourceLocation clang::VisibleModuleSet::getImportLoc ( const Module *  M ) const

inline

Get the location at which the import of a module was triggered.

Definition at line 866 of file Module.h.

Referenced by clang::Sema::ActOnModuleDecl(), and isVisible().

isVisible()

bool clang::VisibleModuleSet::isVisible ( const Module *  M ) const

inline

Determine whether a module is visible.

Definition at line 861 of file Module.h.

References getImportLoc(), and clang::SourceLocation::isValid().

operator=()

VisibleModuleSet & clang::VisibleModuleSet::operator= ( VisibleModuleSet &&  O )

inline

Move from another visible modules set.

Guaranteed to leave the source empty and bump the generation on both.

Definition at line 848 of file Module.h.

setVisible()

void VisibleModuleSet::setVisible	(	Module *	M,
		SourceLocation	Loc,
		VisibleCallback	Vis = [](Module *) {},
		ConflictCallback	Cb = [](ArrayRef<Module *>, Module *,                                           StringRef) {}
	)

Make a specific module visible.
