Events
Arriving messages are transformed into simple events, using message data and metadata.
Simple events sent out of TIBCO BusinessEvents are transformed to the appropriate type of message.
In addition to simple events, which work with incoming and outgoing messages of various sorts, TIBCO BusinessEvents uses a special-purpose event type called SOAPEvent, which inherits from SimpleEvent. It is used for sending and receiving SOAP messages in an HTTP channel. Two other types of events are also used: time events and advisory events.
TIBCO BusinessEvents processes three kinds of events:
- Simple Event
- A representation of a single activity (usually a business activity) that occurred at a single point in time. The SOAPEvent event type inherits from SimpleEvent.
- Time Event
- A timer. Time events can be configured to repeat at intervals, or they can be scheduled using a function in a rule or rule function.
- Advisory Event
- A notice generated by TIBCO BusinessEvents to report an activity in the engine, for example, an exception.
TIBCO BusinessEvents creates instances of simple events and time events based on user-configured event definitions.
- Inheritance
- You can use inheritance when defining simple events.
- Attributes
- In addition to user-defined properties, events have built-in attributes for use in rules and rule functions. For example, simple events have these attributes: @id, @extId, @ttl, and @payload. Concepts and scorecards also have built-in attributes. See TIBCO BusinessEvents Developer’s Guide for details.
