Decorator for "public" functions.
This function should be used for all 'public' functions. That is,
functions usually called from other classes. Note that this should be
applied only to methods (not plain functions), since it expects that the
decorated function is called with a first argument that has a
'_queue_filelock' argument.
Warning:
Use this decorator only after locking.ssynchronized
Example:
@locking.ssynchronized(_LOCK)
@_RequireOpenQueue
def Example(self):
pass
