Class LockHandle

java.lang.Object

org.openspaces.core.map.LockHandle

All Implemented Interfaces:

Externalizable, Serializable

public class LockHandle
extends Object
implements Externalizable

A lock handle allowing to perform map operations when the key is locked. Internally holds the transaction representing the lock and it can be accessed to be passed to any operation that needs to be performed under the same lock.

With GigaMap this is done automatically by just passing the lock handle to an operation.
