Object |
An iterable Object that allows async iteration. When you iterate the returned iterable, each element will be an object representing Queue. The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the documentation for more details and examples. |

// process response
}

times as needed. Note that it can affect your quota.

This method resumes a queue after it has been PAUSED or DISABLED. The state of a queue is stored in the queue's state; after calling this method it will be set to RUNNING.

runTask(request, optionsopt) → {Promise}
Forces a task to run now.
When this method is called, Cloud Tasks will dispatch the task, even if the task is already running, the queue has reached its RateLimits or is PAUSED.
This command is meant to be used for manual debugging. For example, RunTask can be used to retry a failed task after a fix has been made or to manually force a task to be dispatched now.
The dispatched task is returned. That is, the task that is returned contains the status after the task is dispatched but before the task is received by its target.
If Cloud Tasks receives a successful response from the task's target, then the task will be deleted; otherwise the task's schedule_time will be reset to the time that RunTask was called plus the retry delay specified in the queue's RetryConfig.
RunTask returns NOT_FOUND when it is called on a task that has already succeeded or permanently failed.
RunTask cannot be called on a pull task.
