Response for GetTopicAttributes action.

  • 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 the isEmpty() 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

      public final Map<String,String> 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 the From field for notifications to email and email-json endpoints.

      • 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, SignatureVersion is set to 1. The signature is a Base64-encoded SHA1withRSA signature.

        • When you set SignatureVersion to 2. Amazon SNS uses a Base64-encoded SHA256withRSA signature.

          If the API response does not include the SignatureVersion attribute, it means that the SignatureVersion for 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 default TracingConfig is set to PassThrough, and the topic passes through the tracing header it receives from an Amazon SNS publisher to its subscriptions. If set to Active, 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:

      • FifoTopic – When this is set to true, a FIFO topic is created.

      • ContentBasedDeduplication – Enables content-based deduplication for FIFO topics.

        • By default, ContentBasedDeduplication is set to false. If you create a FIFO topic and this attribute is false, you must specify a value for the MessageDeduplicationId parameter for the Publish action.

        • When you set ContentBasedDeduplication to true, Amazon SNS uses a SHA-256 hash to generate the MessageDeduplicationId using 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 MessageDeduplicationId parameter for the Publish action.

      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 the From field for notifications to email and email-json endpoints.

      • 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, SignatureVersion is set to 1. The signature is a Base64-encoded SHA1withRSA signature.

        • When you set SignatureVersion to 2. Amazon SNS uses a Base64-encoded SHA256withRSA signature.

          If the API response does not include the SignatureVersion attribute, it means that the SignatureVersion for 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 default TracingConfig is set to PassThrough, and the topic passes through the tracing header it receives from an Amazon SNS publisher to its subscriptions.

      Specified by:
      toBuilder in class AwsResponse
      Returns:
      a builder for type T

    • builder

      public static GetTopicAttributesResponse.Builder builder()

    • serializableBuilderClass

      public static Class<? extends GetTopicAttributesResponse.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class AwsResponse

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class AwsResponse

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)
      Description copied from class: SdkResponse
      Used to retrieve the value of a field from any class that extends SdkResponse. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, the SdkResponse.getValueForField(String, Class) method will again be available.
      Overrides:
      getValueForField in class SdkResponse
      Parameters:
      fieldName - The name of the member to be retrieved.
      clazz - The class to cast the returned object to.
      Returns:
      Optional containing the casted return value

      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
