    • waitAndApply

      public static <T> CompletableFuture<T> waitAndApply(Function<Executor,CompletableFuture<T>> resultFactory)
      Runs tasks using the prepare-apply model, such as creation of a SaveLoader.
      Parameters:
      resultFactory - a function that takes the apply-stage executor and returns the future
      API Note:
      This method takes a function that supplies an executor to use in the apply stage. Inside the function, callers should run the preparation, and use the passed executor for applying.

      Runs tasks using the prepare-apply model.
      Parameters:
      resultFactory - a function that takes the apply-stage executor and returns the preliminary result
      donePredicate - a predicate that, given the result, checks whether applying has finished
