| Functions | |
|---|---|
| IntrusiveRefCntPtr< FileSystem > | getRealFileSystem () |
| Gets an vfs::FileSystem for the 'real' file system, as seen by the operating system. | |
| std::unique_ptr< FileSystem > | createPhysicalFileSystem () |
| Create an vfs::FileSystem for the 'real' file system, as seen by the operating system. | |
| llvm::sys::fs::UniqueID | getNextVirtualUniqueID () |

◆ collectVFSFromYAML()
Collect all pairs of <virtual path, real path> entries from the YAMLFilePath.
This is used by the module dependency collector to forward the entries into the reproducer output VFS YAML file.
◆ createPhysicalFileSystem()
| std::unique_ptr< FileSystem > llvm::vfs::createPhysicalFileSystem | ( | ) |
|---|
Create an [vfs::FileSystem](classllvm%5F1%5F1vfs%5F1%5F1FileSystem.html "The virtual file system interface.") for the 'real' file system, as seen by the operating system.
It has its own working directory, independent of (but initially equal to) that of the process.
Definition at line 404 of file VirtualFileSystem.cpp.
◆ getDirectoryID()
◆ getFileID()
◆ getNextVirtualUniqueID()
| UniqueID llvm::vfs::getNextVirtualUniqueID | ( | ) |
|---|
◆ getRealFileSystem()
Gets an [vfs::FileSystem](classllvm%5F1%5F1vfs%5F1%5F1FileSystem.html "The virtual file system interface.") for the 'real' file system, as seen by the operating system.
The working directory is linked to the process's working directory. (This is usually thread-hostile).

◆ getUniqueID()
◆ getVFSFromYAML()
Gets a [FileSystem](classllvm%5F1%5F1vfs%5F1%5F1FileSystem.html "The virtual file system interface.") for a virtual file system described in YAML format.
