Detailed Description

A helper class for properly sizing inbound byte buffers and redirecting I/O calls to the proper SocketChannel call.

Many of these calls may seem unnecessary until you consider that they are placeholders for the secure variant, which is much more involved. See ChannelIOSecure for more information.
