Interface Event<TEvent>

This field contains whatever data the sending entity chose to include in this event. The receiving SCXML Processor should reformat this data to match its data model, but must not otherwise modify it.

If this event is generated from an invoked child process, the SCXML Processor must set this field to the invoke id of the invocation that triggered the child process. Otherwise it must leave it blank.

This is a character string giving the name of the event. The SCXML Processor must set the name field to the name of this event. It is what is matched against the 'event' attribute of . Note that transitions can do additional tests by using the value of this field inside boolean expressions in the 'cond' attribute.

This is a URI, equivalent to the 'target' attribute on the element. For external events, the SCXML Processor should set this field to a value which, when used as the value of 'target', will allow the receiver of the event to a response back to the originating entity via the Event I/O Processor specified in 'origintype'. For internal and platform events, the Processor must leave this field blank.

This is equivalent to the 'type' field on the element. For external events, the SCXML Processor should set this field to a value which, when used as the value of 'type', will allow the receiver of the event to a response back to the originating entity at the URI specified by 'origin'. For internal and platform events, the Processor must leave this field blank.

If the sending entity has specified a value for this, the Processor must set this field to that value (see C Event I/O Processors for details). Otherwise, in the case of error events triggered by a failed attempt to send an event, the Processor must set this field to the send id of the triggering element. Otherwise it must leave it blank.

This field describes the event type. The SCXML Processor must set it to: "platform" (for events raised by the platform itself, such as error events), "internal" (for events raised by and with target '_internal') or "external" (for all other events).
