Examples of SubscribeOperation

org.jbpm.pvm.internal.wire.operation.SubscribeOperation
subscribes to an {@link Observable observable}.
The target object can be a {@link Listener}or a specific method to call can be specified (by {@link #setMethodName(String)})

The event can be filtered by specifying a {@link Context} (with {@link #setContextName(String)}), objects to observe (with {@link #setObjectNames(List)}) and events to observe (with {@link #setEventNames(List)}). If the objects or events are not specified, then all objects and events are observed.

The {@link #setWireEvents(boolean)} specifies if the object or the {@link Descriptor} eventsshould be observed.
