Interfaces

Interface	Description
io.netty.util.concurrent.AbstractEventExecutor.LazyRunnable	override SingleThreadEventExecutor.wakesUpForTask(java.lang.Runnable) to re-create this behaviour
io.netty.util.concurrent.SingleThreadEventExecutor.NonWakeupRunnable	override SingleThreadEventExecutor.wakesUpForTask(java.lang.Runnable) to re-create this behaviour
io.netty.util.internal.ObjectPool.ObjectCreator	For removal. Please use Recycler() instead.
io.netty.util.ResourceLeak	please use ResourceLeakTracker as it may lead to false-positives.

Classes

Class	Description
io.netty.util.concurrent.PromiseAggregator	Use PromiseCombiner(EventExecutor). GenericFutureListener implementation which consolidates multiple Futures into one, by listening to individual Futures and producing an aggregated result (success/failure) when all Futures have completed.
io.netty.util.concurrent.UnaryPromiseNotifier	use PromiseNotifier.cascade(boolean, Future, Promise).
io.netty.util.concurrent.UnorderedThreadPoolEventExecutor	The behavior of this event executor deviates from the typical Netty execution model and can cause subtle issues as a result. Applications that wish to process messages with greater parallelism, should instead do explicit off-loading to their own thread-pools.
io.netty.util.DomainMappingBuilder	Use DomainWildcardMappingBuilder instead.
io.netty.util.DomainNameMapping	Use DomainWildcardMappingBuilder}
io.netty.util.DomainNameMappingBuilder	Use DomainWildcardMappingBuilder
io.netty.util.internal.ConcurrentSet	For removal in Netty 4.2. Please use ConcurrentHashMap.newKeySet() instead
io.netty.util.internal.IntegerHolder	For removal in netty 4.2
io.netty.util.internal.logging.CommonsLoggerFactory	Please use Log4J2LoggerFactory or Log4JLoggerFactory or Slf4JLoggerFactory.
io.netty.util.internal.ReferenceCountUpdater	Instead of extending this class, prefer instead to include a RefCnt field and delegate to that. This approach has better compatibility with Graal Native Image.
io.netty.util.internal.ThreadLocalRandom
io.netty.util.ThreadDeathWatcher	will be removed in the next major release

Exceptions

Exceptions	Description
io.netty.util.ResourceLeakException	This class will be removed in the future version.

Annotation Types
