Class Summary

AdminRequest	Administrative request to an agent.
AdminRequest.Start	Requests an agent to start running.
AdminRequest.Stop	Requests an agent to shut down.
ChannelRequest	Requests an agent to perform some action on a given channel.
ChannelRequest.Close	Requests an agent to close the given channel.
ChannelRequest.Register	Requests an agent to register the given SelectionKeyinterest ops with the given channel; The agent will enqueue future responses to the channel onto the given observer stage; If an attachment is given the agent will attach it to the channel's key.
ChannelRequest.WriteData	Requests an agent to completely write ALL of the bytes in the given buffer to the given channel; As usual with NIO, the data is contained between indexes buffer.position() and buffer.limit(), and buffer.remaining() bytes will be written;
ChannelResponse	Response from an agent to a prior ChannelRequest.Registeror ChannelRequest.Close or ChannelRequest.WriteDatarequest; Contains the agent this response originates from, as well as the selection key of the channel the request/response are associated with (retrievable via key.channel()), as well as an optional exception that may have been thrown by the agent in attempting to handle the associated prior request.
ChannelResponse.Accepted	Indicates that an agent has accepted a new channel from a network client (originally initiated by a ChannelRequest.Registerrequest containing SelectionKey OP_ACCEPT ops).
ChannelResponse.Closed	Indicates that an agent has closed a channel (originally initiated by a ChannelRequest.Closerequest).
ChannelResponse.Connected	Indicates that an agent has connected to a network server (originally initiated by a ChannelRequest.Registerrequest containing SelectionKey OP_CONNECT ops).
ChannelResponse.Read	Contains a buffer with the non-blocking data read from the given channel (originally initiated by a prior ChannelRequest.Registerrequest containing SelectionKeyOP_READ ops); The data has buffer.remaining() bytes, and is contained between indexes 0 == buffer.position() and buffer.limit(), as usual with NIO; A buffer with !buffer.hasRemaining() indicates that end-of-stream has been reached for the given channel.
ChannelResponse.Registered	Indicates response is to a prior ChannelRequest.Registerrequest; The interest ops supplied to the original request can be retrieved from the response via response.getInterestOps().
ChannelResponse.Write	Contains a buffer with the data fully written to the given channel (originally initiated by a prior ChannelRequest.WriteData request).
