public class DynamicsExecutionThread2 extends Thread
DynamicsExecutionThread2 builds a command-line invocation string to initiate a Execution (and in-turn Dynamics) process, then launches an entire Java Virtual Machine (JVM) to run it. Communication back to the workbench is via direct socket for commands like playback/pause/kill/goal/status etc. DIS multicast for visualization is also sent out via active Dynamics object. AVCL messages for vehicle-to-vehicle communication/coordination are sent via multicast by the active Execution object. Upon mission completion, option available to send a compressed archive containing the just-completed mission-results file which logs time-stamped telemetry state vectors, control orders, sensor responses, etc.
This interface should be converted to using some sort of listener callback instead of the JTextArea. That would eliminate the Swing import requirement for this class, and be a somewhat cleaner interface. DMcG: Does this really need to be a subclass of Thread?
