Detailed Description

Representation of a network descriptor.

This class represents an network descriptor and provides methods to manipulate the behaviour of the socket. A descriptor represented by this class could be managed by a DescriptorManager. It this managing DescriptorManager is one of the three DescriptorManagers of the Multiplexer, the working method event(enum eventType et) is automatically called if an event has occured on the descriptor.
