com.amazonaws.services.simpleworkflow.model.RespondDecisionTaskCompletedRequest
Container for the parameters to the {@link com.amazonaws.services.simpleworkflow.AmazonSimpleWorkflow#respondDecisionTaskCompleted(RespondDecisionTaskCompletedRequest) RespondDecisionTaskCompleted operation}.
Used by deciders to tell the service that the DecisionTask identified by the taskToken has successfully completed. The decisions argument specifies the list of decisions made while processing the task.

A DecisionTaskCompleted event is added to the workflow history. The executionContext specified is attached to the event in the workflow execution history.
@see com.amazonaws.services.simpleworkflow.AmazonSimpleWorkflow#respondDecisionTaskCompleted(RespondDecisionTaskCompletedRequest)
