    • 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 attributes with their corresponding values.

      The following lists the names, descriptions, and values of the special request parameters that the Subscribe action uses:

      • DeliveryPolicy – The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.

      • FilterPolicy – The simple JSON object that lets your subscriber receive only a subset of messages, rather than receiving every message published to the topic.

      • FilterPolicyScope – This attribute lets you choose the filtering scope by using one of the following string value types:

        • MessageAttributes (default) – The filter is applied on the message attributes.

        • MessageBody – The filter is applied on the message body.

      • RawMessageDelivery – When set to true, enables raw message delivery to Amazon SQS or HTTP/S endpoints. This eliminates the need for the endpoints to process JSON formatting, which is otherwise created for Amazon SNS metadata.

      • RedrivePolicy – When specified, sends undeliverable messages to the specified Amazon SQS dead-letter queue. Messages that can't be delivered due to client errors (for example, when the subscribed endpoint is unreachable) or server errors (for example, when the service that powers the subscribed endpoint becomes unavailable) are held in the dead-letter queue for further analysis or reprocessing.

      The following attribute applies only to Amazon Data Firehose delivery stream subscriptions:

      • SubscriptionRoleArn – The ARN of the IAM role that has the following:

        • Permission to write to the Firehose delivery stream

        • Amazon SNS listed as a trusted entity

        Specifying a valid ARN for this attribute is required for Firehose delivery stream subscriptions. For more information, see Fanout to Firehose delivery streams in the Amazon SNS Developer Guide.

      The following attributes apply only to FIFO topics:

      • ReplayPolicy – Adds or updates an inline policy document for a subscription to replay messages stored in the specified Amazon SNS topic.

      • ReplayStatus – Retrieves the status of the subscription message replay, which can be one of the following:

        • Completed – The replay has successfully redelivered all messages, and is now delivering newly published messages. If an ending point was specified in the ReplayPolicy then the subscription will no longer receive newly published messages.

        • In progress – The replay is currently replaying the selected messages.

        • Failed – The replay was unable to complete.

        • Pending – The default state while the replay initiates.

      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 attributes with their corresponding values.

        • Failed – The replay was unable to complete.

        • Pending – The default state while the replay initiates.

    • returnSubscriptionArn

      public final Boolean returnSubscriptionArn()

      Sets whether the response from the Subscribe request includes the subscription ARN, even if the subscription is not yet confirmed.

      If you set this parameter to true, the response includes the ARN in all cases, even if the subscription is not yet confirmed. In addition to the ARN for confirmed subscriptions, the response also includes the pending subscription ARN value for subscriptions that aren't yet confirmed. A subscription becomes confirmed when the subscriber calls the ConfirmSubscription action with a confirmation token.

      The default value is false.

      Returns:
      Sets whether the response from the Subscribe request includes the subscription ARN, even if the subscription is not yet confirmed.

      If you set this parameter to true, the response includes the ARN in all cases, even if the subscription is not yet confirmed. In addition to the ARN for confirmed subscriptions, the response also includes the pending subscription ARN value for subscriptions that aren't yet confirmed. A subscription becomes confirmed when the subscriber calls the ConfirmSubscription action with a confirmation token.

      The default value is false.

    • toBuilder

      public SubscribeRequest.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<SubscribeRequest.Builder,SubscribeRequest>
      Specified by:
      toBuilder in class SnsRequest
      Returns:
      a builder for type T

    • builder

      public static SubscribeRequest.Builder builder()

    • serializableBuilderClass

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

    • hashCode

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

    • equals

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

    • equalsBySdkFields

      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: SdkRequest
      Used to retrieve the value of a field from any class that extends SdkRequest. 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 SdkRequest.getValueForField(String, Class) method will again be available.
      Overrides:
      getValueForField in class SdkRequest
      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

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
