public interface Channel
extends Comparable<Channel>

A nexus to a network socket or a component which is capable of I/O operations such as read, write, connect, and bind.

A channel provides a user:

• the current state of the channel (e.g. is it open? is it connected?),
• the configuration parameters of the channel (e.g. receive buffer size),
• the I/O operations that the channel supports (e.g. read, write, connect, and bind), and
• the ChannelPipeline which handles all I/O events and requests associated with the channel.

public class Bootstrap
extends Object
implements ExternalResourceReleasable

A helper class which initializes a Channel . This class provides the common data structure for its subclasses which actually initialize  Channel s and their child  Channel s using the common data structure. Please refer to  ClientBootstrap ,  ServerBootstrap , and  ConnectionlessBootstrap  for client side, server-side, and connectionless (e.g. UDP) channel initialization respectively.
