public class Launcher

extends Component

implements java.net.SocketImplFactory

This class is the front end of running real applications on JavaSim/INET. The process involves two steps:

1. Configuring the "map" from the real Internet addresses to JavaSim/INET addresses. This map is used to retrieve the remote address in JavaSim when an application opens a connection with a real Internet address.
2. Launching the application on a node using start(String, String[], Node).

In this framework, we assume:

1. The application class is a standalone Java program (containing the static main() method to start with).
2. The application does not create its own ThreadGroup, or if it does, it does not open a socket in its own ThreadGroup. Note that a GUI application may open socket in the GUI thread group, in which case, the application cannot run on JavaSim without modification.

info

public java.lang.String info()

Description copied from class: Component

Returns information regarding this component. Subclasses should override this method to provide useful information at run-time.

Overrides:
