Interface WorkItem


  • Deprecated. 
    Interfaces for work and work management are replaced by ManagedExecutorService and related interfaces.

    @Deprecated
    public interface WorkItem
    This is returned once a Work is accepted for dispatcher. This is used to retrieve the Work after it's finished and to check any exceptions that it threw.

        Work getResult()
                       throws WorkException
        Deprecated. 
        This returns the Work once the Work completes. It can be interrogated by the application. If the Work threw an exception during run then the exception is rethrown here.
        Throws:
        WorkException
      • getEventTrigger

        java.lang.Object getEventTrigger(java.lang.Class listenerInterface)
        Deprecated. 
        This returns an event proxy. When a method on this proxy is called then if the Work object implements that interface then the corresponding method on the Work object is invoked. The J2EE context of the Work starter is used when invoking the method. The event is executed using an independent transaction.

        If the method called on the proxy returns a value then the return value from the Work object method is returned to the proxy caller.

        If the event method on the target Work object throws an exception while processing the event then this is not propogated to the event publisher. The normal EventSource mechanism of reporting the exception to all listeners implementing EventSourceEvents is used. The only listener on the EventSource associated with a Work object is the Work object it-self. Therefore, if you want to log such exceptions then the Work object should implement EventSourceEvents and the listenerExceptionThrown method will be called if any event method on the Work throws an exception.

        Parameters:
        listenerInterface - This is the type which the returned proxy emulates. The event will only be fired if the Work object implements this interface.
