      public static <V> CompletableFuture<List<V>> combineCancellable(List<? extends CompletableFuture<? extends V>> futures)
      Combines a list of futures into one future that holds a list of their results.

      The returned future is fail-fast; if any of the input futures fails, this returned future will be immediately completed exceptionally than waiting for other input futures. Additionally, all other futures will be canceled.

      Returns:
      the combined future

    • 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

    • lastIndexGetter

      public static <T> ToIntFunction<T> lastIndexGetter(List<T> values)
      Returns a function that, when given a value in values, returns the last index of the value in the list.
      Returns:
      a function that, when given a value in values, returns the last index of the value in the list
      Implementation Note:
      Unlike List.lastIndexOf(java.lang.Object), the returned function will return 0 when given values not in the passed list.

    • lastIndexGetter

      public static <T> ToIntFunction<T> lastIndexGetter(List<T> values, IntFunction<Object2IntMap<T>> mapCreator)
      Returns a function that, when given a value in values, returns the last index of the value in the list.
      Parameters:
      mapCreator - a function that, when given the size of values, returns a map for storing the indices of the values
      Returns:
      a function that, when given a value in values, returns the last index of the value in the list
      Implementation Note:
