Method Details
-
hasAttributes
public final boolean hasAttributes()For responses, this returns true if the service returned a value for the Attributes property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified. -
attributes
A map of the topic's attributes. Attributes in this map include the following:
-
DeliveryPolicy– The JSON serialization of the topic's delivery policy. -
DisplayName– The human-readable name used in theFromfield for notifications toemailandemail-jsonendpoints. -
EffectiveDeliveryPolicy– The JSON serialization of the effective delivery policy, taking system defaults into account. -
Owner– The Amazon Web Services account ID of the topic's owner. -
Policy– The JSON serialization of the topic's access control policy. -
SignatureVersion– The signature version corresponds to the hashing algorithm used while creating the signature of the notifications, subscription confirmations, or unsubscribe confirmation messages sent by Amazon SNS.-
By default,
SignatureVersionis set to 1. The signature is a Base64-encoded SHA1withRSA signature. -
When you set
SignatureVersionto 2. Amazon SNS uses a Base64-encoded SHA256withRSA signature.If the API response does not include the
SignatureVersionattribute, it means that theSignatureVersionfor the topic has value 1.
-
-
SubscriptionsConfirmed– The number of confirmed subscriptions for the topic. -
SubscriptionsDeleted– The number of deleted subscriptions for the topic. -
SubscriptionsPending– The number of subscriptions pending confirmation for the topic. -
TopicArn– The topic's ARN. -
TracingConfig– Tracing mode of an Amazon SNS topic. By defaultTracingConfigis set toPassThrough, and the topic passes through the tracing header it receives from an Amazon SNS publisher to its subscriptions. If set toActive, Amazon SNS will vend X-Ray segment data to topic owner account if the sampled flag in the tracing header is true. This is only supported on standard topics.
The following attribute applies only to server-side-encryption:
-
KmsMasterKeyId- The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SNS or a custom CMK. For more information, see Key Terms. For more examples, see KeyId in the Key Management Service API Reference.
The following attributes apply only to FIFO topics:
-
ArchivePolicy– The policy that sets the retention period for messages stored in the message archive of an Amazon SNS FIFO topic. -
BeginningArchiveTime– The earliest starting point at which a message in the topic’s archive can be replayed from. This point in time is based on the configured message retention period set by the topic’s message archiving policy. -
ContentBasedDeduplication– Enables content-based deduplication for FIFO topics.-
By default,
ContentBasedDeduplicationis set tofalse. If you create a FIFO topic and this attribute isfalse, you must specify a value for theMessageDeduplicationIdparameter for the Publish action. -
When you set
ContentBasedDeduplicationtotrue, Amazon SNS uses a SHA-256 hash to generate theMessageDeduplicationIdusing the body of the message (but not the attributes of the message).(Optional) To override the generated value, you can specify a value for the
MessageDeduplicationIdparameter for thePublishaction.
-
-
FifoTopic– When this is set totrue, a FIFO topic is created.
Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the
hasAttributes()method.- Returns:
- A map of the topic's attributes. Attributes in this map include the following:
-
DeliveryPolicy– The JSON serialization of the topic's delivery policy. -
DisplayName– The human-readable name used in theFromfield for notifications toemailandemail-jsonendpoints. -
EffectiveDeliveryPolicy– The JSON serialization of the effective delivery policy, taking system defaults into account. -
Owner– The Amazon Web Services account ID of the topic's owner. -
Policy– The JSON serialization of the topic's access control policy. -
SignatureVersion– The signature version corresponds to the hashing algorithm used while creating the signature of the notifications, subscription confirmations, or unsubscribe confirmation messages sent by Amazon SNS.-
By default,
SignatureVersionis set to 1. The signature is a Base64-encoded SHA1withRSA signature. -
When you set
SignatureVersionto 2. Amazon SNS uses a Base64-encoded SHA256withRSA signature.If the API response does not include the
SignatureVersionattribute, it means that theSignatureVersionfor the topic has value 1.
