EPEventService Properties

The EPEventService type exposes the following members.

Properties
  NameDescription
Public propertyCurrentTime
Returns current engine time.

If time is provided externally via timer events, the function returns current time as externally provided.

(Inherited from EPEventServiceTimeControl.)
Public propertyNextScheduledTime
Returns the time at which the next schedule execution is expected, returns null if no schedule execution is outstanding.
(Inherited from EPEventServiceTimeControl.)
Public propertyNumEventsEvaluated
Number of events evaluated over the lifetime of the event stream processing runtime, or since the last resetStats() call.
Public propertyUnmatchedListener
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 > 5
In 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.
