Method Summary

Modifier and Type	Method and Description
void	applyViewResult(EventBean[] newData, EventBean[] oldData)
Iterator<EventBean>	getIterator(Viewable parent) Returns the iterator implementing the group-by and aggregation and order-by logic specific to each case of use of these construct.

Method Detail

stop

public void stop()

Description copied from interface: StopCallback

Stops the underlying resources.

Specified by:

stop in interface StopCallback

Overrides:

stop in class ResultSetProcessorRowPerGroupRollup

applyViewResult

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

Specified by:

applyViewResult in interface ResultSetProcessor

Overrides:

applyViewResult in class ResultSetProcessorRowPerGroupRollup

processViewResult

public UniformPair<EventBean[]> processViewResult(EventBean[] newData,
                                                  EventBean[] oldData,
                                                  boolean isSynthesize)

Description copied from interface: ResultSetProcessor

For use by views posting their result, process the event rows that are entered and removed (new and old events). Processes according to select-clauses, group-by clauses and having-clauses and returns new events and old events as specified.

Specified by:

processViewResult in interface ResultSetProcessor

Overrides:

processViewResult in class ResultSetProcessorRowPerGroupRollup

Parameters:

newData - - new events posted by view

oldData - - old events posted by view

isSynthesize - - set to true to indicate that synthetic events are required for an iterator result set

Returns:

pair of new events and old events

getIterator

public Iterator<EventBean> getIterator(Viewable parent)

Description copied from interface: ResultSetProcessor

Returns the iterator implementing the group-by and aggregation and order-by logic specific to each case of use of these construct.

Specified by:

getIterator in interface ResultSetProcessor

Overrides:

getIterator in class ResultSetProcessorRowPerGroupRollup

Parameters:

parent - is the parent view iterator

Returns:

event iterator
