CompletableFutures

public CompletableFutures()

方法详细资料

sequence

public static <T> CompletableFuture<List<T>> sequence(List<CompletableFuture<T>> futures)

sequence

public static <K,V> CompletableFuture<Map<K,V>> sequence(Map<K,CompletableFuture<V>> futures)

supply

public static <T> CompletableFuture<T> supply(java.util.function.Supplier<T> supplier)

call

public static <T> CompletableFuture<T> call(Callable<T> callable)

join

public static <T> T join(CompletableFuture<T> future)

阻塞获取CompletableFuture返回，成功返回对应值，失败抛出异常。 Note：该方法会把受检异常也抛出，而不需要try catch。

CompletableFutures#join(CompletableFuture) 与 CompletableFuture.join() 的区别：

CompletableFutures#join(CompletableFuture)会把实际异常抛出，而不是使用CompletionException封装之后抛出。

类型参数:

T -

参数:

future -

返回:

get

public static <T> T get(CompletableFuture<T> future)
                 throws Throwable

抛出:

Throwable

get

public static <T,X extends Throwable> T get(CompletableFuture<T> future,
                                            java.util.function.Function<? super Throwable,X> exceptionProvider)
                                     throws X extends Throwable

抛出:

X extends Throwable
