A subscription resource. If none of `push_config` or `bigquery_config` is set, then the subscriber will pull and ack messages using API methods. At most one of these fields may be set.
This is the Java data model class that specifies how to parse/serialize into the JSON that is transmitted over HTTP when working with the Cloud Pub/Sub API. For a detailed explanation see: https://developers.google.com/api-client-library/java/google-http-java-client/json

public Subscription()
```
- Method Detail
  - getAckDeadlineSeconds
```
public Integer getAckDeadlineSeconds()
```
    The approximate amount of time (on a best-effort basis) Pub/Sub waits for the subscriber to acknowledge receipt before resending the message. In the interval after the message is delivered and before it is acknowledged, it is considered to be _outstanding_. During that time period, the message will not be redelivered (on a best-effort basis). For pull subscriptions, this value is used as the initial value for the ack deadline. To override this value for a given message, call `ModifyAckDeadline` with the corresponding `ack_id` if using non-streaming pull or send the `ack_id` in a `StreamingModifyAckDeadlineRequest` if using streaming pull. The minimum custom deadline you can specify is 10 seconds. The maximum custom deadline you can specify is 600 seconds (10 minutes). If this parameter is 0, a default value of 10 seconds is used. For push delivery, this value is also used to set the request timeout for the call to the push endpoint. If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message.
    
    Returns:
    
    value or null for none
  - setAckDeadlineSeconds
```

    ackDeadlineSeconds - ackDeadlineSeconds or null for none
  - getBigqueryConfig
```
public BigQueryConfig getBigqueryConfig()

    bigqueryConfig - bigqueryConfig or null for none
  - getDeadLetterPolicy
```
public DeadLetterPolicy getDeadLetterPolicy()
```
    A policy that specifies the conditions for dead lettering messages in this subscription. If dead_letter_policy is not set, dead lettering is disabled. The Cloud Pub/Sub service account associated with this subscriptions's parent project (i.e., service-{project_number}@gcp-sa- pubsub.iam.gserviceaccount.com) must have permission to Acknowledge() messages on this subscription.
    
    Returns:

    Parameters:
    
    deadLetterPolicy - deadLetterPolicy or null for none
  - getDetached
```
public Boolean getDetached()
```
    Indicates whether the subscription is detached from its topic. Detached subscriptions don't receive messages from their topic and don't retain any backlog. `Pull` and `StreamingPull` requests will return FAILED_PRECONDITION. If the subscription is a push subscription, pushes to the endpoint will not be made.
    
    Returns:
    
    value or null for none
  - setDetached
```
public Subscription setDetached(Boolean detached)
```
    Indicates whether the subscription is detached from its topic.

If the subscription is a push subscription, pushes to the endpoint will not be made.
    
    Parameters:
    
    detached - detached or null for none
  - getEnableExactlyOnceDelivery
```
public Boolean getEnableExactlyOnceDelivery()
```
    If true, Pub/Sub provides the following guarantees for the delivery of a message with a given value of `message_id` on this subscription: * The message sent to a subscriber is guaranteed not to be resent before the message's acknowledgement deadline expires. * An acknowledged message will not be resent to a subscriber. Note that subscribers may still receive multiple copies of a message when `enable_exactly_once_delivery` is true if the message was published multiple times by a publisher client. These copies are considered distinct by Pub/Sub and have distinct `message_id` values.
    
    Returns:
    
    value or null for none
  - setEnableExactlyOnceDelivery
```
public Subscription setEnableExactlyOnceDelivery(Boolean enableExactlyOnceDelivery)
```

Note that subscribers may still receive multiple copies of a message when `enable_exactly_once_delivery` is true if the message was published multiple times by a publisher client. These copies are considered distinct by Pub/Sub and have distinct `message_id` values.
    
    Parameters:
    
    enableExactlyOnceDelivery - enableExactlyOnceDelivery or null for none
  - getEnableMessageOrdering
```
public Boolean getEnableMessageOrdering()
```
    If true, messages published with the same `ordering_key` in `PubsubMessage` will be delivered to the subscribers in the order in which they are received by the Pub/Sub system. Otherwise, they may be delivered in any order.
    
    Returns:
    
    value or null for none
  - setEnableMessageOrdering
```
public Subscription setEnableMessageOrdering(Boolean enableMessageOrdering)

    Parameters:
    
    enableMessageOrdering - enableMessageOrdering or null for none
  - getExpirationPolicy
```
public ExpirationPolicy getExpirationPolicy()
```
    A policy that specifies the conditions for this subscription's expiration. A subscription is considered active as long as any connected subscriber is successfully consuming messages from the subscription or is issuing operations on the subscription. If `expiration_policy` is not set, a *default policy* with `ttl` of 31 days will be used. The minimum allowed value for `expiration_policy.ttl` is 1 day. If `expiration_policy` is set, but `expiration_policy.ttl` is not set, the subscription never expires.
    
    Returns:
    
    value or null for none
  - setExpirationPolicy

    Indicates whether to retain acknowledged messages. If true, then messages are not expunged from the subscription's backlog, even if they are acknowledged, until they fall out of the `message_retention_duration` window.
