Detailed Description

Abstract 1 to n connection.

Author:

Marcus Roth

Connection defines an interface for a reliable 1 to n connection. It implements a BinaryDataHandler which is used for reading and writing binary data and OpenSG FieldContainer contents.

Writing to n destinations is easy to handle but reading from n simutanious sending sources is more complicated. To make things easier, you have to select one channel for exclusiv read. This is done by calling selectChannel. Implementations fo selectChannel should select the channel with the most pending data for getting the best read performance.

wait and signal are used to synchronize a number of programms.
