Examples with Subscription com.google.pubsub.v1.Subscription used on opensource projects

Example 11 with Subscription

use of com.google.pubsub.v1.Subscription in project google-cloud-java by GoogleCloudPlatform.

the class SubscriptionAdminClient method modifyAckDeadline.

// AUTO-GENERATED DOCUMENTATION AND METHOD
/**
   * 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.
   *
   * <p>Sample code:
   *
   * <pre><code>
   * try (SubscriptionAdminClient subscriptionAdminClient = SubscriptionAdminClient.create()) {
   *   SubscriptionName subscription = SubscriptionName.create("[PROJECT]", "[SUBSCRIPTION]");
   *   List&lt;String&gt; ackIds = new ArrayList&lt;&gt;();
   *   int ackDeadlineSeconds = 0;
   *   subscriptionAdminClient.modifyAckDeadline(subscription, ackIds, ackDeadlineSeconds);
   * }
   * </code></pre>
   *
   * @param subscription The name of the subscription. Format is
   *     `projects/{project}/subscriptions/{sub}`.
   * @param ackIds List of acknowledgment IDs.
   * @param ackDeadlineSeconds The new ack deadline with respect to the time this request was sent
   *     to the Pub/Sub system. For example, if the value is 10, the new ack deadline will expire 10
   *     seconds after the `ModifyAckDeadline` call was made. Specifying zero may immediately make
   *     the message available for another pull request. The minimum deadline you can specify is 0
   *     seconds. The maximum deadline you can specify is 600 seconds (10 minutes).
   * @throws com.google.api.gax.grpc.ApiException if the remote call fails
