Method Detail

getCopyOf

public java.util.HashMap<K,V> getCopyOf(java.util.HashMap<K,V> hashMap)

Description copied from class: CopyOnWriteTransactionalOwner

returns a copy of the core state object. This is called just before the first write-access to the state. This should not be null;

Specified by:

getCopyOf in class CopyOnWriteTransactionalOwner<java.util.HashMap<K,V>>

prepareForCommit

public void prepareForCommit()
                      throws java.lang.Exception

Description copied from interface: Transactional

Called by transaction manager just before committing a transaction. Any exception thrown by the implementations of this method causes the transaction to be rolled back. This can be viewed as the final point when a transactional entity can "veto" the transaction. The fact that this method is called does not guarantee that the transaction will be committed, since other transactional entities may veto the transaction after this call was made.

This method is invoked outside the TransactionManager lock.

Specified by:

prepareForCommit in interface Transactional

Throws:

java.lang.Exception

_shutdown
