Annotation Type Subscription

@Target(METHOD) @Retention(RUNTIME) @Documented public @interface Subscription
Specifies that the annotated method provides the implementation (ie. the resolver) for a GraphQL subscription.

For example, a user might annotate a method as such: 
 public class StockService {
     @Subscription("stockQuote")
     @Description("Get stock quote changes as they happen")
     public Flow.Publisher<Stock> getStockQuote(String stockCode) {
         //...
     }
 }
Schema generation of this would result in a stanza such as: 
 type Subscription {
    "Get stock quote changes as they happen"
    stockQuote(stockCode: String): Stock
 }
