public interface Lock
This interface is a back-port of the Lock
class that first appeared in J2SE 1.5. Due to a requirement for sophisticated
concurrency, this interface has been back-ported for use in J2SE 1.4 (and greater).
It shares similar method signatures to be consistent with the J2SE 1.5 API.
