Interface ITransportListener

public interface ITransportListener

This is the listener interface for ITransport. This interface must be implemented by every application class that wants to be informed about events related to an ITransport protocol connection. There are two functions, one of which informs about receive data, the other about errors that may occur. It is important to note that both functions will be called in the context of a background thread which is definitely not the Java event dispatcher thread. Thus, the usual considerations about calling GUI functions from different threads apply, e.g. you may only call functions marked as thread-safe in the documentation. All other GUI-related tasks should use the functions of javax.swing.SwingUtilites instead.
