Detailed Description

Represents an open file.

Definition at line 99 of file VirtualFileSystem.h.

Constructor & Destructor Documentation

~File()

File::~File ( )

virtualdefault

Destroy the file after closing it (if open).

Sub-classes should generally call close() inside their destructors. We cannot do that from the base class, since close is virtual.

close()

virtual std::error_code llvm::vfs::File::close ( )

pure virtual

Get the contents of the file as a MemoryBuffer.
