Method Details
-
name
The name of the topic you want to create.
Constraints: Topic names must be made up of only uppercase and lowercase ASCII letters, numbers, underscores, and hyphens, and must be between 1 and 256 characters long.
For a FIFO (first-in-first-out) topic, the name must end with the
.fifo
suffix.- Returns:
- The name of the topic you want to create.

.fifo
suffix.
-
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 attributes with their corresponding values.
The following lists the names, descriptions, and values of the special request parameters that the
CreateTopic
action uses:-
DeliveryPolicy
– The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints. -
DisplayName
– The display name to use for a topic with SMS subscriptions. -
FifoTopic
– Set to true to create a FIFO topic. -
Policy
– The policy that defines who can access your topic. By default, only the topic owner can publish or subscribe to the topic. -
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 to1
. -
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:
-
ArchivePolicy
– Adds or updates an inline policy document to archive messages stored in the specified Amazon SNS 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,
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 attributes with their corresponding values.

hasTags
public final boolean hasTags()For responses, this returns true if the service returned a value for the Tags 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. -
tags
The list of tags to add to a new topic.
To be able to tag a topic on creation, you must have the
sns:CreateTopic
andsns:TagResource
permissions.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

dataProtectionPolicy
The body of the policy document you want to use for this topic.
You can only add one policy per topic.
The policy must be in JSON string format.

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