Allowable event field types
A field in an event can be any Apama data type. The Apama data types are:
boolean decimal float integer string action chunk context dictionary event listener location sequence stream Certain field types are valid only within a certain scope and you cannot pass events with such field types outside that scope. The details are as follows:
context — When an event contains a
context type field, you can send the event to other monitors within the same correlator but you cannot send the event outside the correlator. In other words, you can enqueue or route the event but you cannot emit the event. See
Generating events.
chunk ,
listener and
stream — An event that contains one or more of these types of fields is valid only within the monitor that creates it. You cannot enqueue, route, or emit an event that contains a field of type
chunk,
listener or
stream.
If an event contains a chunk, listener, or stream field you cannot listen for that event.
For details about each type allowed in an event, see
event in the
Apama EPL Reference.
