◆ findEntryByFilename()

const CachedFileSystemEntry * DependencyScanningFilesystemSharedCache::CacheShard::findEntryByFilename ( StringRef Filename ) const

Returns entry associated with the filename or nullptr if none is found.

Definition at line 111 of file DependencyScanningFilesystem.cpp.

References CacheLock, EntriesByFilename, and Filename.

◆ findEntryByUID()

const CachedFileSystemEntry * DependencyScanningFilesystemSharedCache::CacheShard::findEntryByUID ( llvm::sys::fs::UniqueID UID ) const

Returns entry associated with the unique ID or nullptr if none is found.

Definition at line 120 of file DependencyScanningFilesystem.cpp.

◆ getOrEmplaceEntryForFilename()

const CachedFileSystemEntry & DependencyScanningFilesystemSharedCache::CacheShard::getOrEmplaceEntryForFilename	(	StringRef	Filename,
		llvm::ErrorOr< llvm::vfs::Status >	Stat
	)

Returns entry associated with the filename if there is some.

Otherwise, constructs new one with the given status, associates it with the filename and returns the result.

References Filename.

◆ getOrEmplaceEntryForUID()

const CachedFileSystemEntry & DependencyScanningFilesystemSharedCache::CacheShard::getOrEmplaceEntryForUID	(	llvm::sys::fs::UniqueID	UID,
		llvm::vfs::Status	Stat,
		std::unique_ptr< llvm::MemoryBuffer >	Contents
	)

Returns entry associated with the unique ID if there is some.

Otherwise, constructs new one with the given status and contents, associates it with the unique ID and returns the result.

Definition at line 140 of file DependencyScanningFilesystem.cpp.

◆ getOrInsertEntryForFilename()

const CachedFileSystemEntry & DependencyScanningFilesystemSharedCache::CacheShard::getOrInsertEntryForFilename	(	StringRef	Filename,
		const CachedFileSystemEntry &	Entry
	)

Returns entry associated with the filename if there is some.

Otherwise, associates the given entry with the filename and returns it.
