public static interface CfnSubscriptionDefinitionVersion.SubscriptionProperty
A subscription defines a message source, message target, and a topic (or subject) that's used to route messages from the source to the target. A subscription defines the message flow in one direction, from the source to the target. For two-way communication, you must set up two subscriptions, one for each direction.
In an AWS CloudFormation template, the Subscriptions
property of the AWS::Greengrass::SubscriptionDefinitionVersion
resource contains a list of Subscription
property types.
Example:
// The code below shows an example of how to instantiate this type. // The values are placeholders you should change. import software.amazon.awscdk.services.greengrass.*; SubscriptionProperty subscriptionProperty = SubscriptionProperty.builder() .id("id") .source("source") .subject("subject") .target("target") .build();
