com.amazonaws.services.simpleworkflow.model.PollForDecisionTaskRequest
Container for the parameters to the {@link com.amazonaws.services.simpleworkflow.AmazonSimpleWorkflow#pollForDecisionTask(PollForDecisionTaskRequest) PollForDecisionTask operation}.
Used by deciders to get a DecisionTask from the specified decision taskList . A decision task may be returned for any open workflow execution that is using the specified task list. The task includes a paginated view of the history of the workflow execution. The decider should use the workflow type and the history to determine how to properly handle the task.

This action initiates a long poll, where the service holds the HTTP connection open and responds as soon a task becomes available. If no decision task is available in the specified task list before the timeout of 60 seconds expires, an empty result is returned. An empty result, in this context, means that a DecisionTask is returned, but that the value of taskToken is an empty string.

IMPORTANT: Deciders should set their client side socket timeout to at least 70 seconds (10 seconds higher than the timeout).

IMPORTANT: Because the number of workflow history events for a single workflow execution might be very large, the result returned might be split up across a number of pages. To retrieve subsequent pages, make additional calls to PollForDecisionTask using the nextPageToken returned by the initial call. Note that you do not call GetWorkflowExecutionHistory with this nextPageToken. Instead, call PollForDecisionTask again.
