public class FileLock implements AutoClosable

FileLock

All Implemented Interfaces: AutoClosable

Exclusive cooperative interprocess lock on a dedicated lock file. Acquisition waits for the previous holder; the OS releases the lock if the process exits. All writers must use the same lock path. Never delete or replace that file.

try guard = FileLock(Path("settings.lock")):
    Files.writeTextAtomic(Path("settings.json"), "{}")
