Field Detail

NO_CHANGE

protected static final Object NO_CHANGE

Used to fire read event

parent

protected TopiaFiresSupport parent

Each TopiaFiresSupport may have a parent on which events will be propagated. Basically, a TopiaFiresSupport without parent is used by the TopiaApplicationContext, and a TopiaFiresSupport with a parent is used by the TopiaPersistenceContext.

Constructor Detail

TopiaFiresSupport

public TopiaFiresSupport()

Constructor to be used by the TopiaApplicationContext

TopiaFiresSupport

public TopiaFiresSupport(TopiaFiresSupport parent)

Constructor to be used by the TopiaPersistenceContext.

Parameters:

parent - The TopiaApplicationContext's instance

Method Detail

getEntityState

protected EntityState getEntityState(TopiaEntity entity)

Get or create the entity state from the AbstractTopiaListenableSupport.transactionEntities map. This method always returns an instance.
