构造器详细资料

SettableFuture

public SettableFuture()

方法详细资料

set

public boolean set(T value)

Set the value of this future. This method will return true if the value was set successfully, or false if the future has already been set or cancelled.

参数:

value - the value that will be set.

返回:

true if the value was successfully set, else false.

setException

public boolean setException(Throwable exception)

Set the exception of this future. This method will return true if the exception was set successfully, or false if the future has already been set or cancelled.

参数:

exception - the value that will be set.

返回:

true if the exception was successfully set, else false.

cancel

public boolean cancel(boolean mayInterruptIfRunning)

指定者:

cancel 在接口中 Future<T>

isCancelled

public boolean isCancelled()

指定者:

isCancelled 在接口中 Future<T>

isDone

public boolean isDone()

指定者:

isDone 在接口中 Future<T>

get

public T get()
      throws InterruptedException,
             ExecutionException

Retrieve the value.

Will return the value if it has been set via set(Object), throw an ExecutionException if it has been set via setException(Throwable) or throw a CancellationException if it has been cancelled.

指定者:

get 在接口中 Future<T>

返回:

The value associated with this future.

抛出:

InterruptedException

ExecutionException

get

public T get(long timeout,
             TimeUnit unit)
      throws InterruptedException,
             ExecutionException,
             TimeoutException

Retrieve the value.

Will return the value if it has been set via set(Object), throw an ExecutionException if it has been set via setException(Throwable) or throw a CancellationException if it has been cancelled.

指定者:

get 在接口中 Future<T>

参数:

timeout - the maximum time to wait.

unit - the time unit of the timeout argument.

返回:

The value associated with this future.

抛出:

InterruptedException

ExecutionException

TimeoutException

interruptTask

protected void interruptTask()

Subclasses can override this method to implement interruption of the future's computation. The method is invoked automatically by a successful call to cancel(true).

The default implementation does nothing.
