Method Detail
-
isSuccess
boolean isSuccess()
Returnstrue
if and only if the I/O operation was completed successfully.- Returns:
true
if future was completed successfully
-
cause
Throwable cause()
Returns the cause of the failed I/O operation if the I/O operation has failed.- Returns:
- the cause of the failure.
null
if succeeded or this future is not completed yet.
-
getNow
V getNow()
Return the result without blocking. If the future is not done yet this will returnnull
. As it is possible that anull
value is used to mark the future as successful you also need to check if the future is really done withFuture.isDone()
and not relay on the returnednull
value.- Returns:
- object
-
join
@Deprecated V join()
Deprecated.Use toCompletableFuture().join() method instead- Returns:
- the result value
-
await
@Deprecated boolean await(long timeout, TimeUnit unit) throws InterruptedException
Deprecated.Use snippet below instead.try { toCompletableFuture().get(); } catch (Exception e) { // skip }
- Parameters:
timeout
- - wait timeoutunit
- - time unit- Returns:
true
if and only if the future was completed within the specified time limit- Throws:
InterruptedException
- if the current thread was interrupted
-
await
@Deprecated boolean await(long timeoutMillis) throws InterruptedException
Deprecated.Use snippet below instead.try { toCompletableFuture().get(); } catch (Exception e) { // skip }
- Parameters:
timeoutMillis
- - timeout value- Returns:
true
if and only if the future was completed within the specified time limit- Throws:
InterruptedException
- if the current thread was interrupted
-
sync
@Deprecated RFuture<V> sync() throws InterruptedException
Deprecated.Use toCompletableFuture().get() method instead- Returns:
- Future object
- Throws:
InterruptedException
- if the current thread was interrupted
-
syncUninterruptibly
@Deprecated RFuture<V> syncUninterruptibly()
Deprecated.Use toCompletableFuture().join() method instead- Returns:
- Future object
-
await
@Deprecated RFuture<V> await() throws InterruptedException
Deprecated.Use snippet below instead.try { toCompletableFuture().get(); } catch (Exception e) { // skip }
- Returns:
- Future object
- Throws:
InterruptedException
- if the current thread was interrupted
-
awaitUninterruptibly
@Deprecated RFuture<V> awaitUninterruptibly()
Deprecated.Use snippet below instead.try { rFuture.toCompletableFuture().join(); } catch (Exception e) { // skip }
- Returns:
- Future object
-
awaitUninterruptibly
@Deprecated boolean awaitUninterruptibly(long timeout, TimeUnit unit)
Deprecated.Use snippet below instead.try { toCompletableFuture().get(); } catch (Exception e) { // skip }
- Parameters:
timeout
- - timeout valueunit
- - timeout unit value- Returns:
true
if and only if the future was completed within the specified time limit
-
awaitUninterruptibly
@Deprecated boolean awaitUninterruptibly(long timeoutMillis)
Deprecated.Use snippet below instead.try { toCompletableFuture().get(); } catch (Exception e) { // skip }
- Parameters:
timeoutMillis
- - timeout value- Returns:
true
if and only if the future was completed within the specified time limit
-
onComplete
void onComplete(BiConsumer<? super V,? super Throwable> action)
