18 * Simulation Manager is the main class for this module. The Simulation Manager
19 * is used to control the view and control the simulation. Simulation incidents
20 * are loaded, removed, reschedule, and added from the Simulation Manager. The
21 * Simulation Manager provides functionality for connecting to the paramics
22 * communicator and applying diversions. A history of all events is shown as
23 * well.<br>
24 * The SimulationManager may be started at any point before, during, or after a
25 * simulation has begun. The SimulationManager connects to the CADSimulator and
26 * communicates through Java RMI methods. If two SimulationManagers are started,
27 * the second one started, chronologically, will receive communication from the
28 * CADSimulator. <br><br>
29 * The properties file for the SimulationManager class contains the following
30 * data.<br>
31 * <code>
32 * -----------------------------------------------------------------------------<br>
33 * Host Name The host name where the CADSimulator is located.<br>
34 * Error File The target file to use for error logging.<br>
35 * -----------------------------------------------------------------------------<br>
36 * Example File: <br>
37 * CADSimulatorHost = localhost <br>
38 * ErrorFile = sim_mgr_error.xml <br>
39 * -----------------------------------------------------------------------------<br>
