构造器详细资料

SucceededFuture

public SucceededFuture(@Nullable
 V result)

Creates a new instance.

SucceededFuture

public SucceededFuture(@Nullable
 Executor executor,
 @Nullable
 V result)

Creates a new instance.

参数:

executor - the Executor associated with this future

方法详细资料

getCause

public Throwable getCause()

从接口复制的说明: ListenableFuture

Returns the cause of the failed operation if the operation failed.

返回:

the cause of the failure. null if succeeded or this future is not completed yet.

isSuccess

public boolean isSuccess()

从接口复制的说明: ListenableFuture

Returns true if and only if the operation was completed successfully.

getNow

public V getNow()

从接口复制的说明: ListenableFuture

Return the result without blocking. If the future is not done yet this will return null.

As it is possible that a null value is used to mark the future as successful you also need to check if the future is really done with Future.isDone() and not rely on the returned null value.
