Public Member Functions

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

llvm::ErrorOr< llvm::vfs::Status > status (const Twine &Path) override

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

Get a directory_iterator for Dir.

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

Gets real path of Path e.g.

std::error_code isLocal (const Twine &Path, bool &Result) override

Is the file mounted on a local filesystem?

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

Get the working directory of this file system.

std::error_code setCurrentWorkingDirectory (const llvm::Twine &Path) override

Set the working directory.

Public Member Functions inherited from llvm::vfs::FileSystem

~FileSystem () override

virtual llvm::ErrorOr< std::unique_ptr< File > > openFileForReadBinary (const Twine &Path)

Get a File object for the binary file at Path, if one exists.

llvm::ErrorOr< std::unique_ptr< llvm::MemoryBuffer > > getBufferForFile (const Twine &Name, int64_t FileSize=-1, bool RequiresNullTerminator=true, bool IsVolatile=false, bool IsText=true)

This is a convenience method that opens a file, gets its content and then closes the file.

virtual bool exists (const Twine &Path)

Check whether Path exists.

virtual std::error_code makeAbsolute (SmallVectorImpl< char > &Path) const

Make Path an absolute path.

void print (raw_ostream &OS, PrintType Type=PrintType::Contents, unsigned IndentLevel=0) const

virtual void visitChildFileSystems (VisitCallbackTy Callback)

Constructor & Destructor Documentation

◆ FileCollectorFileSystem()

llvm::FileCollectorFileSystem::FileCollectorFileSystem ( IntrusiveRefCntPtr< vfs::FileSystem > FS,

std::shared_ptr< FileCollector > Collector )

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.
