Class FileLockManager

java.lang.Object
  ariba.util.core.ObjectLockManager
      ariba.util.io.FileLockManager

public class FileLockManager
extends ObjectLockManager

Maintains a set of files that can be locked exclusively. The lock is actually set on the file's underlying canonical path, not on the File object. Thus, two File objects that reference the same underlying file will resolve to the same lock. If there's an exception when looking up the canonical path, then the underlying uncanonical path is used.
