@interface DelegateAsync

An AST transformation that takes each method in the given class and adds a delegate method that returns a grails.async.Promise and executes the method asynchronously. For example given the following class:

 class BookApi {
    List listBooksByTitle(String title) { }
 }
 

 @DelegateAsync(BookApi)
 class AsyncBookApi {}
 

 class AsyncBookApi {
     private BookApi $bookApi
     Promise> listBooksByTitle(String title) {
        (Promise>)Promises.createPromise {
            $bookApi.listBooksByTitle(title)
        }
     }
 }
