![]() | EPEventService Properties |
The EPEventService type exposes the following members.
Name | Description | |
---|---|---|
![]() | CurrentTime |
Returns current engine time.
If time is provided externally via timer events, the function returns current time as externally provided.
(Inherited from EPEventServiceTimeControl.) |
![]() | NextScheduledTime |

outstanding.
(Inherited from EPEventServiceTimeControl.) |
![]() | NumEventsEvaluated |
Number of events evaluated over the lifetime of the event stream processing runtime,
or since the last resetStats() call.
|
![]() | UnmatchedListener |
Sets a listener to receive events that are unmatched by any statement.
Events that can be unmatched are all events that are send into a runtime via one of the sendEvent methods, or that have been generated via insert-into clause. For an event to be unmatched by any statement, the event must not match any statement's event stream filter criteria (a where-clause is NOT a filter criteria for a stream, as below). Note: In the following statement a MyEvent event does always match this statement's event stream filter criteria, regardless of the value of the 'quantity' property. select * from MyEvent where quantity > 5In the following statement only a MyEvent event with a 'quantity' property value of 5 or less does not match this statement's event stream filter criteria: select * from MyEvent(quantity > 5) For patterns, if no pattern sub-expression is active for such event, the event is also unmatched. |
