Method Detail

promiseNotifyingBiConsumer

public static <SuccessT,PromiseT> BiConsumer<SuccessT,? super Throwable> promiseNotifyingBiConsumer(Function<SuccessT,PromiseT> successFunction,
                                                                                                    io.netty.util.concurrent.Promise<PromiseT> promise)

Creates a BiConsumer that notifies the promise of any failures either via the Throwable passed into the BiConsumer of as a result of running the successFunction.

Type Parameters:

SuccessT - Success type.

PromiseT - Type being fulfilled by the promise.

Parameters:

successFunction - Function called to process the successful result and map it into the result to notify the promise with.

promise - Promise to notify of success or failure.

Returns:

BiConsumer that can be used in a CompletableFuture.whenComplete(BiConsumer) method.

asyncPromiseNotifyingBiConsumer

public static <SuccessT,PromiseT> BiConsumer<SuccessT,? super Throwable> asyncPromiseNotifyingBiConsumer(BiConsumer<SuccessT,io.netty.util.concurrent.Promise<PromiseT>> successConsumer,
                                                                                                         io.netty.util.concurrent.Promise<PromiseT> promise)

Creates a BiConsumer that notifies the promise of any failures either via the throwable passed into the BiConsumer or as a result of running the successConsumer. This assumes that the successConsumer will notify the promise when it completes successfully.

Type Parameters:

SuccessT - Success type.

PromiseT - Type being fulfilled by the Promise.

Parameters:

successConsumer - BiConsumer to call if the result is successful. Promise is also passed and must be notified on success.

promise - Promise to notify.

Returns:

BiConsumer that can be used in a CompletableFuture.whenComplete(BiConsumer) method.

promiseNotifyingListener

public static <T> io.netty.util.concurrent.GenericFutureListener<io.netty.util.concurrent.Future<T>> promiseNotifyingListener(io.netty.util.concurrent.Promise<T> channelPromise)

Create a GenericFutureListener that will notify the provided Promise on success and failure.

Parameters:

channelPromise - Promise to notify.

Returns:

GenericFutureListener

doInEventLoop

public static void doInEventLoop(io.netty.util.concurrent.EventExecutor eventExecutor,
                                 Runnable runnable)

Runs a task in the given EventExecutor. Runs immediately if the current thread is in the eventExecutor.

Parameters:

eventExecutor - Executor to run task in.

runnable - Task to run.

doInEventLoop

public static void doInEventLoop(io.netty.util.concurrent.EventExecutor eventExecutor,
                                 Runnable runnable,
                                 io.netty.util.concurrent.Promise<?> promise)

Runs a task in the given EventExecutor. Runs immediately if the current thread is in the eventExecutor. Notifies the given Promise if a failure occurs.

Parameters:

eventExecutor - Executor to run task in.

runnable - Task to run.

promise - Promise to notify if failure occurs.
