Examples of com.amazonaws.services.simpleworkflow.flow.generic.ActivityImplementation.execute()

com.amazonaws.services.simpleworkflow.flow.generic.ActivityImplementation.execute()
Execute external activity or initiate its execution if {@link #isManualActivityCompletion()} is true. @param task information about activity to be executed. Use {@link ActivityTask#getInput()} to get activity inputarguments. @return result of activity execution if {@link #isManualActivityCompletion()} is setto false. Use {@link ActivityWorker#respondActivityTaskCompleted(String,Map)}to return result in asynchronous case.

            ActivityExecutionContext context = new ActivityExecutionContextImpl(service, domain, task);

            if (activityImplementation == null) {
                throw new ActivityFailureException("Unknown activity type: " + activityType);
