Constructor & Destructor Documentation

◆ FileCollectorFileSystem()

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

Definition at line 257 of file FileCollector.cpp.

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 276 of file FileCollector.cpp.

References Collector, and llvm::X86AS::FS.

◆ 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 296 of file FileCollector.cpp.

References llvm::X86AS::FS.

◆ getRealPath()

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

Definition at line 281 of file FileCollector.cpp.

References Collector, and llvm::X86AS::FS.

◆ isLocal()

std::error_code llvm::FileCollectorFileSystem::isLocal ( const Twine Path,
bool &  Result 
)
inlineoverridevirtual

Is the file mounted on a local filesystem?

Reimplemented from llvm::vfs::FileSystem.

Definition at line 292 of file FileCollector.cpp.

References llvm::X86AS::FS.

◆ openFileForRead()

llvm::ErrorOr<std::unique_ptr<llvm::vfs::File> > llvm::FileCollectorFileSystem::openFileForRead ( const Twine Path)
inlineoverridevirtual

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

Implements llvm::vfs::FileSystem.

Definition at line 269 of file FileCollector.cpp.

References Collector, and llvm::X86AS::FS.

◆ setCurrentWorkingDirectory()

std::error_code llvm::FileCollectorFileSystem::setCurrentWorkingDirectory ( const llvm::Twine Path)
inlineoverridevirtual

Set the working directory.

This will affect all following operations on this file system and may propagate down for nested file systems.

Implements llvm::vfs::FileSystem.

Definition at line 300 of file FileCollector.cpp.

References llvm::X86AS::FS.

◆ status()

llvm::ErrorOr<llvm::vfs::Status> llvm::FileCollectorFileSystem::status ( const Twine Path)
inlineoverridevirtual

Get the status of the entry at Path, if one exists.

Implements llvm::vfs::FileSystem.

Definition at line 261 of file FileCollector.cpp.
