Class Promises.Results

org.forgerock.util.promise.Promises.Results

Enclosing class:

Promises

public static class Promises.Results
extends Object

Ordered list of joined asynchronous results.

Order of the results is guaranteed to be the same as the order of joined promises, so that results can be accessed safely using their index with get(int).

     
     Promise<String, IOException> p1 = ...
     Promise<Integer, Exception> p2 = ...
     Promises.join(Arrays.asList(p1, p2))
             .then(results -> {
               String text = results.get(0);
               int times = results.get(1);
               return text + "" + times;
             })
