Member Function Documentation

PTHManager * PTHManager::Create	(	const std::string &	file,
		DiagnosticsEngine &	Diags
	)		`[static]`

Create - This method creates PTHManager objects. The 'file' argument is the name of the PTH file. This method returns NULL upon failure.

Definition at line 438 of file PTHLexer.cpp.

References clang::OnDiskChainedHashTable< Info >::Create(), InvalidPTH(), clang::io::ReadLE32(), clang::io::ReadUnalignedLE16(), clang::DiagnosticsEngine::Report(), and Version.

PTHLexer * PTHManager::CreateLexer ( FileID FID )

CreateLexer - Return a PTHLexer that "lexes" the cached tokens for the specified file. This method returns NULL if no cached tokens exist. It is the responsibility of the caller to 'delete' the returned object.

Definition at line 590 of file PTHLexer.cpp.

References data(), clang::OnDiskChainedHashTable< Info >::end(), clang::OnDiskChainedHashTable< Info >::find(), clang::SourceManager::getFileEntryForID(), clang::Preprocessor::getSourceManager(), PTHLexer, and clang::io::ReadLE32().

FileSystemStatCache * PTHManager::createStatCache ( )

createStatCache - Returns a FileSystemStatCache object for use with FileManager objects. These objects use the PTH data to speed up calls to stat by memoizing their results from when the PTH file was generated.

Definition at line 708 of file PTHLexer.cpp.

IdentifierInfo * PTHManager::get ( StringRef Name ) [virtual]

get - Return the identifier token info for the specified named identifier. Unlike the version in IdentifierTable, this returns a pointer instead of a reference. If the pointer is NULL then the IdentifierInfo cannot be found.

Implements clang::IdentifierInfoLookup.

Definition at line 576 of file PTHLexer.cpp.

References clang::OnDiskChainedHashTable< Info >::end(), and clang::OnDiskChainedHashTable< Info >::find().

const char* clang::PTHManager::getOriginalSourceFile ( ) const [inline]

getOriginalSourceFile - Return the full path to the original header file name that was used to generate the PTH cache.
