.SH NAME
ivy-java - a software bus library
.SH SYNOPSIS
Ivy-java provides a useful set of Java library classes for communicating between different
processes through a software bus
.SH DESCRIPTION
Ivy is a software bus, ie a system that allows any software component to freely exchange data.
The basic principle of a software bus is to ease the rapid implementation of new agents, and to manage a dynamic collection of agents on the bus: agents connect, send and receive messages, and disconnect without perturbing the overall functionment of the bus.
Each time an application initializes a connection on the bus, a
"ready" message is sent to all other applications already connected, and the
list of the messages subscribed by this application is dispatched.
The format for the messages is free.
.nf
The essential classes of Ivy Java are:
.nf
.I Ivy: 
\ API for the connexion to the software bus
.nf
.I IvyWatcher: 
\ to handle UDP socket
.nf
.I IvyMessageListener: 
\ to receive messages
.nf
.I IvyApplicationListener: 
\ contains 4 virtual methods for handling connexion/deconnexion, die and direct messages
.nf
.I IvyApplicationAdapter: 
\ to implement the IvyApplicationListener methods
