dispatch

boolean dispatch()

Dispatch events of the insert and remove stream of named windows to consumers, as part of the main event processing or dispatch loop.

Returns:

send events to consuming statements

addDispatch

void addDispatch(NamedWindowConsumerLatchFactory latchFactory,
                 NamedWindowDeltaData delta,
                 java.util.Map<EPStatementAgentInstanceHandle,java.util.List<NamedWindowConsumerView>> consumers)

For use to add a result of a named window that must be dispatched to consuming views.

Parameters:

delta - is the result to dispatch

consumers - is the destination of the dispatch, a map of statements to one or more consuming views

destroy

void destroy()

Destroy service.
