Method Detail

acknowledge

public Pubsub.Projects.Subscriptions.Acknowledge acknowledge(java.lang.String subscription,
                                                    AcknowledgeRequest content)
                                                      throws java.io.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 - The subscription whose message is being acknowledged.

content - the AcknowledgeRequest

Returns:

the request

Throws:

java.io.IOException

create

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

Creates a subscription to a given topic. 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. 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 - 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:

java.io.IOException

                                            throws java.io.IOException

Deletes an existing subscription. All pending messages 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 - The subscription to delete.

Returns:

the request

Throws:

java.io.IOException

                                      throws java.io.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:

Returns:

the request
