Subscription criteria builder

Subscription criteria builder

For type safety, we don't want to be typing Subscription criteria manually where it's possible. Instead, we are generating it. For example

new Criteria.BlueprintNameCriteria("hello").and(new Criteria.ResourceActionNameCriteria(Subscription.ResourceAction.CHANGE_LEASE))

This will be expanded to the following Javascript in the Subscription:

(event.data.blueprintId == "hello") && (event.data.actionName == "ChangeLease") 

Common criteria have their own wrapper classes for convenience.

• BlueprintNameCriteria
• EventTypeCriteria
• ResourceActionNameCriteria

Alternatively, you can create a new custom Criteria:

new Criteria("my script")
