Class ComponentizedSimulator

public class ComponentizedSimulator

extends Object

This version of the simulator model is designed to use components models of the objects and to directly interact with UAVs and UCAVs via ChannelBundles. This class is designed to act as a representation of the world. In implementaiton, it looks strikingly like a server model. Mutation is done internally through MethodRequest objects. Only appropriate objects are allowed to change the simulation state via internal method calls.
