Detailed Description

Callback that records textual includes and direct modular includes/imports during preprocessing.

At the end of the main file, it also collects transitive modular dependencies and passes everything to the DependencyConsumer of the parent ModuleDepCollector.

◆ EndOfMainFile()

void ModuleDepCollectorPP::EndOfMainFile ( )

overridevirtual

Callback invoked when the end of the main file is reached.

No subsequent callbacks will be made.

Reimplemented from clang::PPCallbacks.

Definition at line 517 of file ModuleDepCollector.cpp.

◆ InclusionDirective()

void ModuleDepCollectorPP::InclusionDirective	(	SourceLocation	HashLoc,
		const Token &	IncludeTok,
		StringRef	FileName,
		bool	IsAngled,
		CharSourceRange	FilenameRange,
		OptionalFileEntryRef	File,
		StringRef	SearchPath,
		StringRef	RelativePath,
		const Module *	SuggestedModule,
		bool	ModuleImported,
		SrcMgr::CharacteristicKind	FileType
	)

overridevirtual

Callback invoked whenever an inclusion directive of any kind (#include, #import, etc.) has been processed, regardless of whether the inclusion will actually result in an inclusion.

Parameters

HashLoc	The location of the '#' that starts the inclusion directive.
IncludeTok	The token that indicates the kind of inclusion directive, e.g., 'include' or 'import'.
FileName	The name of the file being included, as written in the source code.
IsAngled	Whether the file name was enclosed in angle brackets; otherwise, it was enclosed in quotes.
FilenameRange	The character range of the quotes or angle brackets for the written file name.
File	The actual file that may be included by this inclusion directive.
SearchPath	Contains the search path which was used to find the file in the file system. If the file was found via an absolute include path, SearchPath will be empty. For framework includes, the SearchPath and RelativePath will be split up. For example, if an include of "Some/Some.h" is found via the framework path "path/to/Frameworks/Some.framework/Headers/Some.h", SearchPath will be "path/to/Frameworks/Some.framework/Headers" and RelativePath will be "Some.h".
RelativePath	The path relative to SearchPath, at which the include file was found. This is equal to FileName except for framework includes.
SuggestedModule	The module suggested for this header, if any.
ModuleImported	Whether this include was translated into import of `SuggestedModule`.
FileType	The characteristic kind, indicates whether a file or directory holds normal user code, system code, or system code which is implicitly 'extern "C"' in C++ mode.

◆ LexedFileChanged()

void ModuleDepCollectorPP::LexedFileChanged	(	FileID	FID,
		LexedFileChangeReason	Reason,
		SrcMgr::CharacteristicKind	FileType,
		FileID	PrevFID,
		SourceLocation	Loc
	)

overridevirtual

Callback invoked whenever the Lexer moves to a different file for lexing.

Unlike FileChanged line number directives and other related pragmas do not trigger callbacks to LexedFileChanged.

Parameters

FID	The `FileID` that the `Lexer` moved to.
Reason	Whether the `Lexer` entered a new file or exited one.
FileType	The `CharacteristicKind` of the file the `Lexer` moved to.
PrevFID	The `FileID` the `Lexer` was using before the change.
Loc	The location where the `Lexer` entered a new file from or the location that the `Lexer` moved into after exiting a file.

Reimplemented from clang::PPCallbacks.

◆ moduleImport()

void ModuleDepCollectorPP::moduleImport	(	SourceLocation	ImportLoc,
		ModuleIdPath	Path,
		const Module *	Imported
	)

overridevirtual

Callback invoked whenever there was an explicit module-import syntax.

Parameters

ImportLoc	The location of import directive token.
Path	The identifiers (and their locations) of the module "path", e.g., "std.vector" would be split into "std" and "vector".
Imported	The imported module; can be null if importing failed.
