Detailed Description
The services are called from state machines via the mechanism described in SCXML Specification - 6.4 <invoke>. This class represents an actual instance of an invoked service.
Property Documentation
id : const QString
This property holds the ID of the invokable service.
The ID is specified by the id attribute of the <invoke> element.
Access functions:
| virtual QString | id() const = 0 |
name : const QString
This property holds the name of the service being invoked.
Access functions:
| virtual QString | name() const = 0 |
parentStateMachine : QScxmlStateMachine* const
This property holds the SCXML state machine that invoked the service.
Access functions:
| QScxmlStateMachine * | parentStateMachine() const |
Member Function Documentation
[pure virtual] void QScxmlInvokableService::postEvent(QScxmlEvent *event)
Sends an event to the service.
[pure virtual] bool QScxmlInvokableService::start()
Starts the invokable service. Returns true on success, or false if the invocation fails.
