Brn.Gui

The Brn.Gui is a user interface for the Brn.Sim simulator. It is able to control the simulation execution like a debugger. It visualizes simulation results which are specified in simulation code via the Brn.Measure framework. Furthermore, it is also a result browser for already completed simulations which were executed by the Brn.DistSim distributed simulation framework and stored in the Brn.Db storage.

The Brn.Gui is a stand-alone Eclipse RCP application. A Brn.Sim instance can be connected to the Brn.Gui via Java RMI. The out-of-process architecture (and the resulting RMI overhead) is mainly technical: the usage of custom classloader during simulation causes several problems which RMI solves through serialization.
