Member Data Documentation

llvm::MD5::MD5Result clang::ASTUnit::PreambleFileHash::MD5

Memory buffers have MD5 instead of modification time. We don't compute MD5 for on-disk files because we hope that modification time is enough to tell if the file was changed.

time_t clang::ASTUnit::PreambleFileHash::ModTime

Modification time is set for files that are on disk. For memory buffers it is zero.

off_t clang::ASTUnit::PreambleFileHash::Size

All files have size set.
