◆ findRealPathByFilename()
| const CachedRealPath * DependencyScanningFilesystemSharedCache::CacheShard::findRealPathByFilename | ( | StringRef | Filename | ) | const |
Returns the real path associated with the filename or nullptr if none is found.
Definition at line 198 of file DependencyScanningFilesystem.cpp.
References CacheByFilename, CacheLock, and clang::nullptr.
◆ getOrEmplaceRealPathForFilename()
| const CachedRealPath & DependencyScanningFilesystemSharedCache::CacheShard::getOrEmplaceRealPathForFilename | ( | StringRef | Filename, |
| llvm::ErrorOr< StringRef > | RealPath ) |
Returns the real path associated with the filename if there is some.
Otherwise, constructs new one with the given one, associates it with the filename and returns the result.
