All Implemented Interfaces:

public class DetectorHandler
extends javax.safetycritical.AperiodicEventHandler

DetectorHandler instances carry out the actual collisions detection. Each DetectorHandler takes in a list of lists of motions, each set contains the motions that span cross a same voxel. The collisions detection carried out here considers the Z axis, and also updates the collisions number recorded in the CDxMission. If this DetectorHanndler has finished, it updates its state in DetectorControl.

Field Summary

DetectorControl	control To get the control of DetectorControl.
int	id The Identity of this DetectorHandler.
CDxMission	mission To get the control of the current mission.

Constructor Summary

DetectorHandler(CDxMission mission, DetectorControl control, int id, javax.safetycritical.AperiodicEvent event_bound)
Constructor

Method Summary

int	CalcPartCollisions() Method to get the allocated list of lists of motions by its ID, and detect collisions
int	determineCollisions(List motions) Compute the number of collisions for a List of Motion objects.
void	handleEvent() Major actions happen within handlerEvent() including calculation, updation of the number of collisions, and notification to DetectorControl.
