Constructor Detail

EnhancedTransaction

public EnhancedTransaction(PMWrapper pm)

Method Detail

fixState

protected void fixState(java.lang.Object object)

called when the PM for a transactional object is closed. This gives the Transaction the opportunity to save this object and make it usable. For enhanced objects, this is accomplished by making the old proxy discard the (now defunct) transactional object, and instead point to the read-only version of the same object.
