public class TopicPolicy
extends Resource

The policy for an SNS Topic.

Policies define the operations that are allowed on this resource.

You almost never need to define this construct directly.

All AWS resources that support resource policies have a method called addToResourcePolicy(), which will automatically create a new resource policy if one doesn't exist yet, otherwise it will add to the existing policy.

Prefer to use addToResourcePolicy() instead.

Example:

 Topic topic = new Topic(this, "Topic");
 PolicyDocument policyDocument = PolicyDocument.Builder.create()
         .assignSids(true)
         .statements(List.of(
             PolicyStatement.Builder.create()
                     .actions(List.of("sns:Subscribe"))
                     .principals(List.of(new AnyPrincipal()))
                     .resources(List.of(topic.getTopicArn()))
                     .build()))
         .build();
 TopicPolicy topicPolicy = TopicPolicy.Builder.create(this, "Policy")
         .topics(List.of(topic))
         .policyDocument(policyDocument)
         .build();
