public class SnsPublish
extends TaskStateBase

A Step Functions Task to publish messages to SNS topic.

Example:

 EvaluateExpression convertToSeconds = EvaluateExpression.Builder.create(this, "Convert to seconds")
         .expression("$.waitMilliseconds / 1000")
         .resultPath("$.waitSeconds")
         .build();
 EvaluateExpression createMessage = EvaluateExpression.Builder.create(this, "Create message")
         // Note: this is a string inside a string.
         .expression("`Now waiting ${$.waitSeconds} seconds...`")
         .runtime(Runtime.NODEJS_LATEST)
         .resultPath("$.message")
         .build();
 SnsPublish publishMessage = SnsPublish.Builder.create(this, "Publish message")
         .topic(new Topic(this, "cool-topic"))
         .message(TaskInput.fromJsonPathAt("$.message"))
         .resultPath("$.sns")
         .build();
 Wait wait = Wait.Builder.create(this, "Wait")
         .time(WaitTime.secondsPath("$.waitSeconds"))
         .build();
 StateMachine.Builder.create(this, "StateMachine")
         .definition(convertToSeconds.next(createMessage).next(publishMessage).next(wait))
         .build();
