Class SoftLock<V>

java.lang.Object
  org.ehcache.transactions.xa.SoftLock<V>

All Implemented Interfaces:

java.io.Serializable

public class SoftLock<V>
extends java.lang.Object
implements java.io.Serializable

SoftLocks are the value containers stored in the underlying store by the XAStore. A SoftLock contains three essential things:

• The transaction ID responsible for inserting the SoftLock, or null if the transaction is terminated.
• The old value, i.e.: the value that is going to be stored upon transaction rollback, or null if there was no value.
• The new value holder, i.e.: the value holder that is going to be stored upon transaction commit, or null if the mapping is to be removed.
