getAckDeadlineSeconds()
public int 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 <i>outstanding</i>. 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.
int32 ack_deadline_seconds = 5;
| Type | Description |
| int | The ackDeadlineSeconds.

getDeadLetterPolicy()
public DeadLetterPolicy getDeadLetterPolicy()
A policy that specifies the conditions for dead lettering messages in

permission to Acknowledge() messages on this subscription.

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.

getEnableMessageOrdering()

any order.

getExpirationPolicy()
public ExpirationPolicy getExpirationPolicy()

default policy with ttl of 31 days will be used. The minimum allowed
value for expiration_policy.ttl is 1 day.

|
getFilterBytes()
