Specified by:: build in class io.grpc.stub.AbstractStub<CloudTasksGrpc.CloudTasksStub>

listQueues

public void listQueues(ListQueuesRequest request,
                       io.grpc.stub.StreamObserver<ListQueuesResponse> responseObserver)

 Lists queues.
 Queues are returned in lexicographical order.

getQueue

public void getQueue(GetQueueRequest request,
                     io.grpc.stub.StreamObserver<Queue> responseObserver)

 Gets a queue.

createQueue

public void createQueue(CreateQueueRequest request,
                        io.grpc.stub.StreamObserver<Queue> responseObserver)

 Creates a queue.
 Queues created with this method allow tasks to live for a maximum of 31
 days. After a task is 31 days old, the task will be deleted regardless of
 whether it was dispatched or not.
 WARNING: Using this method may have unintended side effects if you are
 using an App Engine `queue.yaml` or `queue.xml` file to manage your queues.
 Read
 [Overview of Queue Management and
 queue.yaml](https://cloud.google.com/tasks/docs/queue-yaml) before using
 this method.

public void updateQueue(UpdateQueueRequest request,
                        io.grpc.stub.StreamObserver<Queue> responseObserver)

 Updates a queue.
 This method creates the queue if it does not exist and updates
 the queue if it does exist.
 Queues created with this method allow tasks to live for a maximum of 31
 days. After a task is 31 days old, the task will be deleted regardless of
 whether it was dispatched or not.
 WARNING: Using this method may have unintended side effects if you are
 using an App Engine `queue.yaml` or `queue.xml` file to manage your queues.

 [Overview of Queue Management and
 queue.yaml](https://cloud.google.com/tasks/docs/queue-yaml) before using
 this method.

deleteQueue

public void deleteQueue(DeleteQueueRequest request,
                        io.grpc.stub.StreamObserver<com.google.protobuf.Empty> responseObserver)

 Deletes a queue.
 This command will delete the queue even if it has tasks in it.
 Note: If you delete a queue, a queue with the same name can't be created
 for 7 days.
 WARNING: Using this method may have unintended side effects if you are
 using an App Engine `queue.yaml` or `queue.xml` file to manage your queues.

 [Overview of Queue Management and
 queue.yaml](https://cloud.google.com/tasks/docs/queue-yaml) before using
 this method.

purgeQueue

public void purgeQueue(PurgeQueueRequest request,
                       io.grpc.stub.StreamObserver<Queue> responseObserver)

 Purges a queue by deleting all of its tasks.
 All tasks created before this method is called are permanently deleted.
 Purge operations can take up to one minute to take effect. Tasks
 might be dispatched before the purge takes effect. A purge is irreversible.

pauseQueue

public void pauseQueue(PauseQueueRequest request,
                       io.grpc.stub.StreamObserver<Queue> responseObserver)

 Pauses the queue.
 If a queue is paused then the system will stop dispatching tasks
 until the queue is resumed via
 [ResumeQueue][google.cloud.tasks.v2beta3.CloudTasks.ResumeQueue]. Tasks can
 still be added when the queue is paused. A queue is paused if its
 [state][google.cloud.tasks.v2beta3.Queue.state] is
 [PAUSED][google.cloud.tasks.v2beta3.Queue.State.PAUSED].

resumeQueue

public void resumeQueue(ResumeQueueRequest request,
                        io.grpc.stub.StreamObserver<Queue> responseObserver)

 Resume a queue.
 This method resumes a queue after it has been
 [PAUSED][google.cloud.tasks.v2beta3.Queue.State.PAUSED] or
 [DISABLED][google.cloud.tasks.v2beta3.Queue.State.DISABLED]. The state of a
 queue is stored in the queue's
 [state][google.cloud.tasks.v2beta3.Queue.state]; after calling this method
 it will be set to
 [RUNNING][google.cloud.tasks.v2beta3.Queue.State.RUNNING].
 WARNING: Resuming many high-QPS queues at the same time can
 lead to target overloading. If you are resuming high-QPS
 queues, follow the 500/50/5 pattern described in
 [Managing Cloud Tasks Scaling
 Risks](https://cloud.google.com/tasks/docs/manage-cloud-task-scaling).

getIamPolicy

public void getIamPolicy(com.google.iam.v1.GetIamPolicyRequest request,
                         io.grpc.stub.StreamObserver<com.google.iam.v1.Policy> responseObserver)

 Gets the access control policy for a
 [Queue][google.cloud.tasks.v2beta3.Queue]. Returns an empty policy if the
 resource exists and does not have a policy set.
 Authorization requires the following
 [Google IAM](https://cloud.google.com/iam) permission on the specified
 resource parent:
 * `cloudtasks.queues.getIamPolicy`

setIamPolicy

public void setIamPolicy(com.google.iam.v1.SetIamPolicyRequest request,
                         io.grpc.stub.StreamObserver<com.google.iam.v1.Policy> responseObserver)

 Sets the access control policy for a
 [Queue][google.cloud.tasks.v2beta3.Queue]. Replaces any existing policy.
 Note: The Cloud Console does not check queue-level IAM permissions yet.
 Project-level permissions are required to use the Cloud Console.
 Authorization requires the following
 [Google IAM](https://cloud.google.com/iam) permission on the specified
 resource parent:
 * `cloudtasks.queues.setIamPolicy`

testIamPermissions

public void testIamPermissions(com.google.iam.v1.TestIamPermissionsRequest request,
                               io.grpc.stub.StreamObserver<com.google.iam.v1.TestIamPermissionsResponse> responseObserver)

 Returns permissions that a caller has on a
 [Queue][google.cloud.tasks.v2beta3.Queue]. If the resource does not exist,
 this will return an empty set of permissions, not a
 [NOT_FOUND][google.rpc.Code.NOT_FOUND] error.
 Note: This operation is designed to be used for building permission-aware
 UIs and command-line tools, not for authorization checking. This operation
 may "fail open" without warning.

listTasks

public void listTasks(ListTasksRequest request,
                      io.grpc.stub.StreamObserver<ListTasksResponse> responseObserver)

 Lists the tasks in a queue.
 By default, only the [BASIC][google.cloud.tasks.v2beta3.Task.View.BASIC]
 view is retrieved due to performance considerations;
 [response_view][google.cloud.tasks.v2beta3.ListTasksRequest.response_view]
 controls the subset of information which is returned.
 The tasks may be returned in any order. The ordering may change at any
 time.

getTask

public void getTask(GetTaskRequest request,
                    io.grpc.stub.StreamObserver<Task> responseObserver)

 Gets a task.

createTask

public void createTask(CreateTaskRequest request,
                       io.grpc.stub.StreamObserver<Task> responseObserver)

 Creates a task and adds it to a queue.
 Tasks cannot be updated after creation; there is no UpdateTask command.
 * The maximum task size is 100KB.

deleteTask

public void deleteTask(DeleteTaskRequest request,
                       io.grpc.stub.StreamObserver<com.google.protobuf.Empty> responseObserver)

 Deletes a task.
 A task can be deleted if it is scheduled or dispatched. A task
 cannot be deleted if it has executed successfully or permanently
 failed.

runTask

public void runTask(RunTaskRequest request,
                    io.grpc.stub.StreamObserver<Task> responseObserver)

 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][google.cloud.tasks.v2beta3.RateLimits] or is
 [PAUSED][google.cloud.tasks.v2beta3.Queue.State.PAUSED].
 This command is meant to be used for manual debugging. For
 example, [RunTask][google.cloud.tasks.v2beta3.CloudTasks.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][Task.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][google.cloud.tasks.v2beta3.Task.schedule_time] will be
 reset to the time that
 [RunTask][google.cloud.tasks.v2beta3.CloudTasks.RunTask] was called plus
 the retry delay specified in the queue's
 [RetryConfig][google.cloud.tasks.v2beta3.RetryConfig].
 [RunTask][google.cloud.tasks.v2beta3.CloudTasks.RunTask] returns
 [NOT_FOUND][google.rpc.Code.NOT_FOUND] when it is called on a
 task that has already succeeded or permanently failed.

bufferTask

public void bufferTask(BufferTaskRequest request,
                       io.grpc.stub.StreamObserver<BufferTaskResponse> responseObserver)

 Creates and buffers a new task without the need to explicitly define a Task
 message. The queue must have [HTTP
 target][google.cloud.tasks.v2beta3.HttpTarget]. To create the task with a
 custom ID, use the following format and set TASK_ID to your desired ID:
 projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks/TASK_ID:buffer
 To create the task with an automatically generated ID, use the following
 format:
 projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_ID/tasks:buffer.
 Note: This feature is in its experimental stage. You must request access to
 the API through the [Cloud Tasks BufferTask Experiment Signup
 form](https://forms.gle/X8Zr5hiXH5tTGFqh8).
