Examples of com.hazelcast.core.MultiMap.forceUnlock()

com.hazelcast.core.MultiMap.forceUnlock()
Releases the lock for the specified key regardless of the lock owner. It always successfully unlocks the key, never blocks and returns immediately.

Warning:
This method uses hashCode and equals of binary form of the key, not the actual implementations of hashCode and equals defined in key's class. @param key key to lock.
