Detailed Description

Represents the result of a path lookup into the RedirectingFileSystem.

Constructor & Destructor Documentation

◆ LookupResult()

RedirectingFileSystem::LookupResult::LookupResult	(	Entry *	E,
		sys::path::const_iterator	Start,
		sys::path::const_iterator	End )

Definition at line 2272 of file VirtualFileSystem.cpp.

References llvm::sys::path::append(), assert(), llvm::dyn_cast(), and E.

Member Function Documentation

◆ getExternalRedirect()

std::optional< StringRef > llvm::vfs::RedirectingFileSystem::LookupResult::getExternalRedirect ( ) const

inline

If the found Entry maps the input path to a path in the external file system (i.e.

it is a FileEntry or DirectoryRemapEntry), returns that path.

Definition at line 936 of file VirtualFileSystem.h.

References llvm::dyn_cast(), E, and llvm::isa().

◆ getPath()

void RedirectingFileSystem::LookupResult::getPath ( llvm::SmallVectorImpl< char > & Path ) const

Get the (canonical) path of the found entry.

This uses the as-written path components from the VFS specification.
