Event Processing Agent
Event processing component; Event processing mediator
A software module and a node in the event processing network that process events .
Filter agent: receives a single event and decides based on a predicate expression whether to route this event further or not (in this case it is a terminal node for this specific event instance).
Validation agent: receives a single event and a predicate expression that serves as an integrity constraint for this event. If the integrity constraint is violated may act as a filter (reject the event), may transform the event, or may orchestrate additional actions in an event sink.
Transformation agent: receives a single event and transforms this event to another event format.
