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.

waitAndApply

public static <T> T waitAndApply(Function<Executor,T> resultFactory,

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

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.
