Method Detail

getNumChangesetRows

public int getNumChangesetRows()

Specified by:

getNumChangesetRows in class OutputProcessView

getOptionalOutputCondition

public OutputCondition getOptionalOutputCondition()

Specified by:

getOptionalOutputCondition in class OutputProcessView

update

public void update(EventBean[] newData,
                   EventBean[] oldData)

The update method is called if the view does not participate in a join.

Parameters:

newData - - new events

oldData - - old events

process

public void process(Set<MultiKey<EventBean>> newEvents,
                    Set<MultiKey<EventBean>> oldEvents,
                    ExprEvaluatorContext exprEvaluatorContext)

This process (update) method is for participation in a join.

Parameters:

newEvents - - new events

oldEvents - - old events

exprEvaluatorContext - expression evaluation context

postProcess

protected void postProcess(boolean force,
                           UniformPair<EventBean[]> newOldEvents,
                           UpdateDispatchView childView)

iterator

public Iterator<EventBean> iterator()

Description copied from interface: Viewable

Allows iteration through all elements in this viewable. The iterator will return the elements in the collection in their natural order, or, if there is no natural ordering, in some unpredictable order.

Returns:

an iterator which will go through all current elements in the collection.

terminated

public void terminated()
