/**
 * <p>Used by deciders to get a <a>DecisionTask</a> from the specified decision
 *         <code>taskList</code>. 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.</p>
 *          <p>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.</p>
 *          <important>
 *             <p>Deciders should set their client side socket timeout to at least 70 seconds (10
 *         seconds higher than the timeout).</p>
 *          </important>
 *          <important>
 *             <p>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 <code>PollForDecisionTask</code> using the
 *           <code>nextPageToken</code> returned by the initial call. Note that you do
 *           <i>not</i> call <code>GetWorkflowExecutionHistory</code> with this
 *           <code>nextPageToken</code>. Instead, call <code>PollForDecisionTask</code>
 *         again.</p>
 *          </important>
 *          <p>
 *             <b>Access Control</b>
 *          </p>
 *          <p>You can use IAM policies to control this action's access to Amazon SWF resources as
 *       follows:</p>
 *          <ul>
 *             <li>
 *                <p>Use a <code>Resource</code> element with the domain name to limit the action to
 *           only specified domains.</p>
 *             </li>
 *             <li>
 *                <p>Use an <code>Action</code> element to allow or deny permission to call this
 *           action.</p>
 *             </li>
 *             <li>
 *                <p>Constrain the <code>taskList.name</code> parameter by using a
 *             <code>Condition</code> element with the <code>swf:taskList.name</code> key to allow the
 *           action to access only certain task lists.</p>
 *             </li>
 *          </ul>
 *          <p>If the caller doesn't have sufficient permissions to invoke the action, or the
 *       parameter values fall outside the specified constraints, the action fails. The associated
 *       event attribute's <code>cause</code> parameter is set to <code>OPERATION_NOT_PERMITTED</code>.
 *       For details and example IAM policies, see <a href="https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html">Using IAM to Manage Access to Amazon SWF
 *         Workflows</a> in the <i>Amazon SWF Developer Guide</i>.</p>
