Direct Known Subclasses:

BluetoothConnection, SerialPortConnection, SocketConnection

public abstract class Connection
extends Observable

A Connection is a model (in MVC sense) of a connection. It holds the connection information necessary for making a particular type of connection (e.g. serial / bluetooth / socket / etc...). Each Connection also returns a GUI panel that allows the user to enter connection information. Connections are Observable so that the ConnectionDialog can check if the "Connect" button should be enabled any time a change is made.
