FileInfo

cajeta.io.file.FileInfo — snapshot of a single stat call: size, timestamps, type flags, and permission bits for one filesystem entry, captured in one syscall so callers avoid per-attribute round-trips. Read the public fields directly: size, createdNanos / modifiedNanos / accessedNanos (Unix nanoseconds as int64), isFile / isDir / isSymlink, and permissions. The flags mirror the cheaper single-attribute probes on Path; prefer this type when you need several attributes at once. A stat-touching accessor on Path that returns a populated FileInfo is planned; until then the only constructor is the zero-initialized no-arg form.

FileInfo meta = heap FileInfo();
meta.size = (int64) 1024;
meta.isFile = true;
boolean regular = meta.isFile && !meta.isDir;
int64 mtime = meta.modifiedNanos;    // Unix nanoseconds
