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 theFrom
field for notifications toemail
andemail-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 theSignatureVersion
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 defaultTracingConfig
is 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:
-
FifoTopic
– When this is set totrue
, a FIFO topic is created. -
ContentBasedDeduplication
– Enables content-based deduplication for FIFO topics.-
By default,
ContentBasedDeduplication
is set tofalse
. If you create a FIFO topic and this attribute isfalse
, you must specify a value for theMessageDeduplicationId
parameter for the Publish action. -
When you set
ContentBasedDeduplication
totrue
, Amazon SNS uses a SHA-256 hash to generate theMessageDeduplicationId
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 thePublish
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 theFrom
field for notifications toemail
andemail-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 theSignatureVersion
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 defaultTracingConfig
is 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:
-
FifoTopic
– When this is set totrue
, a FIFO topic is created. -
ContentBasedDeduplication
– Enables content-based deduplication for FIFO topics.-
By default,
ContentBasedDeduplication
is set tofalse
. If you create a FIFO topic and this attribute isfalse
, you must specify a value for theMessageDeduplicationId
parameter for the Publish action. -
When you set
ContentBasedDeduplication
totrue
, Amazon SNS uses a SHA-256 hash to generate theMessageDeduplicationId
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 thePublish
action.

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:

equalsBySdkFields
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 anSdkPojo
class, and is generated based on a service model.If an
SdkPojo
class does not have any inherited fields,equalsBySdkFields
andequals
are essentially the same.- Specified by:
equalsBySdkFields
in interfaceSdkPojo
- Parameters:
obj
- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.
-
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. -
getValueForField
Description copied from class:SdkResponse
Used to retrieve the value of a field from any class that extendsSdkResponse
. 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, theSdkResponse.getValueForField(String, Class)
method will again be available.- Overrides:
getValueForField
in classSdkResponse
- 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
