/**
 * Container for the parameters to the {@link com.amazonaws.services.simpleworkflow.AmazonSimpleWorkflow#countPendingActivityTasks(CountPendingActivityTasksRequest) CountPendingActivityTasks operation}.
 * <p>
 * Returns the estimated number of activity tasks in the specified task list. The count returned is an approximation and is not guaranteed to be exact.
 * If you specify a task list that no activity task was ever scheduled in then 0 will be returned.
 * </p>
 * <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>Use a <code>Resource</code> element with the domain name to limit the action to only specified domains.</li>
 * <li>Use an <code>Action</code> element to allow or deny permission to call this action.</li>
 * <li>Use a <b>Condition</b> element with the <code>swf:taskList.name</code> key to allow the action to access only certain task lists.</li>
 * 
 * </ul>
 * <p>
 * If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action
 * fails by throwing <code>OperationNotPermitted</code> . For details and example IAM policies, see <a
 * href="http://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html"> Using IAM to Manage Access to Amazon SWF Workflows </a> .
