	Get the status of the entry at `Path`, if one exists.
llvm::ErrorOr< std::unique_ptr< llvm::vfs::File > >	openFileForRead (const Twine &Path) override
	Get a `File` object for the text file at `Path`, if one exists.
llvm::vfs::directory_iterator	dir_begin (const llvm::Twine &Dir, std::error_code &EC) override

Constructor & Destructor Documentation

◆ FileCollectorFileSystem()

llvm::FileCollectorFileSystem::FileCollectorFileSystem	(	IntrusiveRefCntPtr< vfs::FileSystem >	FS,
		std::shared_ptr< FileCollector >	Collector )

inlineexplicit

Definition at line 259 of file FileCollector.cpp.

References llvm::move().

Member Function Documentation

◆ dir_begin()

llvm::vfs::directory_iterator llvm::FileCollectorFileSystem::dir_begin	(	const llvm::Twine &	Dir,
		std::error_code &	EC )

inlineoverridevirtual

Get a directory_iterator for Dir.

Note: The 'end' iterator is directory_iterator().

Implements llvm::vfs::FileSystem.

Definition at line 278 of file FileCollector.cpp.

◆ getCurrentWorkingDirectory()

llvm::ErrorOr< std::string > llvm::FileCollectorFileSystem::getCurrentWorkingDirectory ( ) const

inlineoverridevirtual

Get the working directory of this file system.

Implements llvm::vfs::FileSystem.

Definition at line 298 of file FileCollector.cpp.

◆ getRealPath()

std::error_code llvm::FileCollectorFileSystem::getRealPath	(	const Twine &	Path,
		SmallVectorImpl< char > &	Output )

inlineoverridevirtual

Gets real path of Path e.g.

collapse all . and .. patterns, resolve symlinks. For real file system, this uses llvm::sys::fs::real_path. This returns errc::operation_not_permitted if not implemented by subclass.

Reimplemented from llvm::vfs::FileSystem.
