Method Detail

create

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

Creates a snapshot from the requested subscription. Snapshots are used in Seek 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. If the snapshot already exists, returns `ALREADY_EXISTS`. If the requested subscription doesn't exist, returns `NOT_FOUND`. If the backlog in the subscription is too old -- and the resulting snapshot would expire in less than 1 hour -- then `FAILED_PRECONDITION` is returned. See also the `Snapshot.expire_time` field. If the name is not provided in the request, the server will assign a random name for this snapshot on the same project as the subscription, conforming to the [resource name format](https://cloud.google.com/pubsub/docs/admin#resource_names). The generated name is populated in the returned Snapshot object. Note that for REST API requests, you must specify a name in the request. Create a request for the method "snapshots.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. User-provided name for this snapshot. If the name is not provided in the request, the server will assign a random name for this snapshot on the same project as the subscription. Note that for REST API requests, you must specify a name. See the resource name rules. Format is `projects/{project}/snapshots/{snap}`.

content - the CreateSnapshotRequest

Returns:

the request

Throws:

java.io.IOException

delete

public Pubsub.Projects.Snapshots.Delete delete(java.lang.String snapshot)
                                        throws java.io.IOException

Removes an existing snapshot. Snapshots are used in Seek 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. When the snapshot is deleted, all messages retained in the snapshot are immediately dropped. After a snapshot is deleted, a new one may be created with the same name, but the new one has no association with the old snapshot or its subscription, unless the same subscription is specified. Create a request for the method "snapshots.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:

snapshot - Required. The name of the snapshot to delete. Format is `projects/{project}/snapshots/{snap}`.

Returns:

the request

Throws:

java.io.IOException

get

public Pubsub.Projects.Snapshots.Get get(java.lang.String snapshot)
                                  throws java.io.IOException

Gets the configuration details of a snapshot. Snapshots are used in Seek 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. Create a request for the method "snapshots.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:

snapshot - Required. The name of the snapshot to get. Format is `projects/{project}/snapshots/{snap}`.

Returns:

the request

Throws:

java.io.IOException

getIamPolicy

public Pubsub.Projects.Snapshots.GetIamPolicy getIamPolicy(java.lang.String resource)
                                                    throws java.io.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 "snapshots.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:

java.io.IOException

list

public Pubsub.Projects.Snapshots.List list(java.lang.String project)
                                    throws java.io.IOException

Lists the existing snapshots. Snapshots are used in Seek 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. Create a request for the method "snapshots.list". 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:

project - Required. The name of the project in which to list snapshots. Format is `projects/{project-id}`.

testIamPermissions

public Pubsub.Projects.Snapshots.TestIamPermissions testIamPermissions(java.lang.String resource,

Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.
