  • Type Parameters:
    T - for two
    Enclosing class:
    Async
    public static interface Async.CombinedBuilder<T>

      Modifier and Type Method Description
      void add​(java.util.concurrent.CompletableFuture<T> completableFuture)
      This adds a CompletableFuture into the collection of results
      void addObject​(java.lang.Object object)
      This adds a new value which can be either a materialized value or a CompletableFuture
      java.util.concurrent.CompletableFuture<java.util.List<T>> await()
      This will return a CompletableFuture<List<T>> even if the inputs are all materialized values
