ConnectionManager
The primary interface to the low-level networking layer in this package.
Definition: connectionManager.h:41
ConnectionWriter
This class handles threaded delivery of datagrams to various TCP or UDP sockets.
Definition: connectionWriter.h:35
Connection
Represents a single TCP or UDP socket for input or output.
Definition: connection.h:29
LightReMutex
A lightweight reentrant mutex.
Definition: lightReMutex.h:32
NetAddress
Represents a network address to which UDP packets may be sent or to which a TCP socket may be bound.
Definition: netAddress.h:25
NetDatagram
A specific kind of Datagram, especially for sending across or receiving from a network.
Definition: netDatagram.h:40
ReferenceCount
A base class for all things that want to be reference-counted.
Definition: referenceCount.h:38
Socket_IP
Base functionality for a INET domain Socket This call should be the starting point for all other unix...
