Method Detail

acknowledge

public Pubsub.Projects.Subscriptions.Acknowledge acknowledge(String subscription,
                                                             AcknowledgeRequest content)
                                                      throws IOException

Acknowledges the messages associated with the `ack_ids` in the `AcknowledgeRequest`. The Pub/Sub system can remove the relevant messages from the subscription. Acknowledging a message whose ack deadline has expired may succeed, but such a message may be redelivered later. Acknowledging a message more than once will not result in an error. Create a request for the method "subscriptions.acknowledge". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

Parameters:

subscription - Required. The subscription whose message is being acknowledged. Format is `projects/{project}/subscriptions/{sub}`.

content - the AcknowledgeRequest

Returns:

the request

Throws:

IOException

create

public Pubsub.Projects.Subscriptions.Create create(String name,
                                                   Subscription content)
                                            throws IOException

Creates a subscription to a given topic. See the [resource name rules] (https://cloud.google.com/pubsub/docs/admin#resource_names). If the subscription already exists, returns `ALREADY_EXISTS`. If the corresponding topic doesn't exist, returns `NOT_FOUND`. If the name is not provided in the request, the server will assign a random name for this subscription on the same project as the topic, conforming to the [resource name format] (https://cloud.google.com/pubsub/docs/admin#resource_names). The generated name is populated in the returned Subscription object. Note that for REST API requests, you must specify a name in the request. Create a request for the method "subscriptions.create". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

Parameters:

name - Required. The name of the subscription. It must have the format `"projects/{project}/subscriptions/{subscription}"`. `{subscription}` must start with a letter, and contain only letters (`[A-Za-z]`), numbers (`[0-9]`), dashes (`-`), underscores (`_`), periods (`.`), tildes (`~`), plus (`+`) or percent signs (`%`). It must be between 3 and 255 characters in length, and it must not start with `"goog"`.

content - the Subscription

Returns:

the request

Throws:

IOException

delete

public Pubsub.Projects.Subscriptions.Delete delete(String subscription)
                                            throws IOException

Deletes an existing subscription. All messages retained in the subscription are immediately dropped. Calls to `Pull` after deletion will return `NOT_FOUND`. After a subscription is deleted, a new one may be created with the same name, but the new one has no association with the old subscription or its topic unless the same topic is specified. Create a request for the method "subscriptions.delete". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

Parameters:

subscription - Required. The subscription to delete. Format is `projects/{project}/subscriptions/{sub}`.

Returns:

the request

Throws:

IOException

detach

public Pubsub.Projects.Subscriptions.Detach detach(String subscription)
                                            throws IOException

Detaches a subscription from this topic. All messages retained in the subscription are dropped. Subsequent `Pull` and `StreamingPull` requests will return FAILED_PRECONDITION. If the subscription is a push subscription, pushes to the endpoint will stop. Create a request for the method "subscriptions.detach". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

Parameters:

subscription - Required. The subscription to detach. Format is `projects/{project}/subscriptions/{subscription}`.

Returns:

the request

Throws:

IOException

get

public Pubsub.Projects.Subscriptions.Get get(String subscription)
                                      throws IOException

Gets the configuration details of a subscription. Create a request for the method "subscriptions.get". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

Parameters:

subscription - Required. The name of the subscription to get. Format is `projects/{project}/subscriptions/{sub}`.

Returns:

the request

Throws:

IOException

getIamPolicy

public Pubsub.Projects.Subscriptions.GetIamPolicy getIamPolicy(String resource)
                                                        throws IOException

Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set. Create a request for the method "subscriptions.getIamPolicy". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

Parameters:

resource - REQUIRED: The resource for which the policy is being requested. See the operation documentation for the appropriate value for this field.

Returns:

the request

Throws:

IOException

the request

Throws:

IOException

modifyAckDeadline

public Pubsub.Projects.Subscriptions.ModifyAckDeadline modifyAckDeadline(String subscription,
                                                                         ModifyAckDeadlineRequest content)
                                                                  throws IOException

Modifies the ack deadline for a specific message. This method is useful to indicate that more time is needed to process a message by the subscriber, or to make the message available for redelivery if the processing was interrupted. Note that this does not modify the subscription- level `ackDeadlineSeconds` used for subsequent messages. Create a request for the method "subscriptions.modifyAckDeadline". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

Parameters:

subscription - Required. The name of the subscription. Format is `projects/{project}/subscriptions/{sub}`.

content - the ModifyAckDeadlineRequest

Returns:

the request

Throws:

IOException

modifyPushConfig

public Pubsub.Projects.Subscriptions.ModifyPushConfig modifyPushConfig(String subscription,
                                                                       ModifyPushConfigRequest content)
                                                                throws IOException

Modifies the `PushConfig` for a specified subscription. This may be used to change a push subscription to a pull one (signified by an empty `PushConfig`) or vice versa, or change the endpoint URL and other attributes of a push subscription. Messages will accumulate for delivery continuously through the call regardless of changes to the `PushConfig`. Create a request for the method "subscriptions.modifyPushConfig". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

Parameters:

subscription - Required. The name of the subscription. Format is `projects/{project}/subscriptions/{sub}`.

content - the ModifyPushConfigRequest

Returns:

the request

Throws:

IOException

public Pubsub.Projects.Subscriptions.Patch patch(String name,
                                                 UpdateSubscriptionRequest content)
                                          throws IOException

Updates an existing subscription. Note that certain properties of a subscription, such as its topic, are not modifiable. Create a request for the method "subscriptions.patch". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

                                        throws IOException

Pulls messages from the server. The server may return `UNAVAILABLE` if there are too many concurrent pull requests pending for the given subscription. Create a request for the method "subscriptions.pull". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

Parameters:

subscription - Required. The subscription from which messages should be pulled. Format is `projects/{project}/subscriptions/{sub}`.

seek

public Pubsub.Projects.Subscriptions.Seek seek(String subscription,
                                               SeekRequest content)
                                        throws IOException

Seeks an existing subscription to a point in time or to a given snapshot, whichever is provided in the request. Snapshots are used in [Seek] (https://cloud.google.com/pubsub/docs/replay- overview) operations, which allow you to manage message acknowledgments in bulk. That is, you can set the acknowledgment state of messages in an existing subscription to the state captured by a snapshot. Note that both the subscription and the snapshot must be on the same topic. Create a request for the method "subscriptions.seek". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

Parameters:

subscription - Required. The subscription to affect.

content - the SeekRequest

Returns:

the request

Throws:

IOException

setIamPolicy

public Pubsub.Projects.Subscriptions.SetIamPolicy setIamPolicy(String resource,
                                                               SetIamPolicyRequest content)
                                                        throws IOException

Sets the access control policy on the specified resource. Replaces any existing policy. Can return `NOT_FOUND`, `INVALID_ARGUMENT`, and `PERMISSION_DENIED` errors. Create a request for the method "subscriptions.setIamPolicy". This request holds the parameters needed by the pubsub server. After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

After setting any optional parameters, call the AbstractGoogleClientRequest.execute() method to invoke the remote operation.

Parameters:

resource - REQUIRED: The resource for which the policy detail is being requested. See the operation documentation for the appropriate value for this field.

content - the TestIamPermissionsRequest

Returns:

the request
