Method Detail

addResultSetListener

public void addResultSetListener(@Nonnull
                                 ResultSetListener listener)

removeResultSetListener

public void removeResultSetListener(ResultSetListener listener)

ResultSetProducer.removeResultSetListener(ResultSetListener)

fireResultSetEvent

public void fireResultSetEvent(@Nullable
                               ResultSetAndUpdateCountCollection results)

Notifies all registered listeners of the new result set. The event's source is the ResultSetProducer specified to this instance's constructor.

Calling this method has the side effect of incrementing the eventsFired property by exactly 1.

Parameters:

results - The new result sets. If it is already a CachedRowSet, it will be embedded in the event object as-is; otherwise, it will be copied into a new CachedRowSet. In the latter case, the row cursor of results will have been moved to the afterLast position as a side effect of populating the new CachedRowSet. Furthermore, for the CachedRowSet to populate properly, the row cursor of results should be at the beforeFirst position prior to calling this method.

getEventsFired

public long getEventsFired()

Returns the count of how many times #fireResultSetEvent(ResultSet) has been called.
