Class VWConnection

java.lang.Object

execution.network.VWConnection

Direct Known Subclasses:

AuvVWConnection, DisVWConnection, MunitionVWConnection, UavVWConnection, UgvVWConnection, UsvVWConnection

public abstract class VWConnection
extends Object

Handles network communication between the vehicle and the virtual world as required Simulates network comms if Execution and Dynamics are run in same thread Class must be extended to implement model/vehicle-specific telemetry strings
