Interface LockManager

All Superinterfaces:

Lifecycle

All Known Implementing Classes:

DistributedLockManager, SemaphoreLockManager

public interface LockManager
extends Lifecycle

Manages a set of named read/write locks. A global lock is represented by a null object. Obtaining a named read or write lock should implicitly obtain a global read lock. Consequently, all named locks are blocked if a global write lock is obtained.
