io.netty.channel

Interface EventLoop

All Superinterfaces:

AutoCloseable, EventExecutor, EventExecutorGroup, EventLoopGroup, Executor, ExecutorService, ScheduledExecutorService

All Known Implementing Classes:

AbstractEventLoop, DefaultEventLoop, NioEventLoop, SingleThreadEventLoop, ThreadPerChannelEventLoop

public interface EventLoop
extends EventExecutor, EventLoopGroup

Will handle all the I/O operations for a Channel once registered. One EventLoop instance will usually handle more then one Channel but this may depend on implementation details and internals.

Method Detail

parent

EventLoopGroup parent()

Description copied from interface: EventExecutor

Return the EventExecutorGroup which is the parent of this EventExecutor,

Specified by:

parent in interface EventExecutor

unwrap

EventLoop unwrap()

Description copied from interface: EventExecutor

Returns an EventExecutor that is not a WrappedEventExecutor.

• A WrappedEventExecutor implementing this method must return the underlying EventExecutor while making sure that it's not a WrappedEventExecutor (e.g. by multiple calls to EventExecutor.unwrap()).
• An EventExecutor that is not a WrappedEventExecutor must return a reference to itself.
• This method must not return null.

Specified by:

unwrap in interface EventExecutor

asInvoker

ChannelHandlerInvoker asInvoker()

Creates a new default ChannelHandlerInvoker implementation that uses this EventLoop to invoke event handler methods.
