Method Details

handleMatching

public void handleMatching(EventBean[] triggerEvents,
 EventBean[] matchingEvents)

Description copied from class: OnExprViewNameWindowBase

Implemented by on-trigger views to action on the combination of trigger and matching events in the named window.

Specified by:

handleMatching in class OnExprViewNameWindowBase

Parameters:

triggerEvents - is the trigger events (usually 1)

matchingEvents - is the matching events retrieved via lookup strategy

buildJoinResult

public static Set<MultiKeyArrayOfKeys<EventBean>> buildJoinResult(EventBean[] triggerEvents,
 EventBean[] matchingEvents)

getEventType

public EventType getEventType()

Description copied from interface: Viewable

Provides metadata information about the type of object the event collection contains.

Returns:

metadata for the objects in the collection

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.
