Class CDxMission

java.lang.Object
  javax.safetycritical.Mission
      cdx.CDxMission

public class CDxMission
extends javax.safetycritical.Mission

The single mission of the parallel CDx. The seven handlers of the mission are InputFrameHandler, ReducerHandler, DetectorHandler (four instances), and OutputCollisionsHandler.

Field Summary

int	collisions Records the number of collisions calculated by the detector handlers.
DetectorControl	control Control object used to orchestrate execution of the handlers.
RawFrame	currentFrame Records the current radar frame.
StateTable	state Records previous aircraft positions.
Partition	work Records a partition of the computational work as it is distributed between the parallel detection handlers.

Constructor Summary

CDxMission()
Constructor

Method Summary

int	getColls() This method returns the cumulative number of collisions recorded.
RawFrame	getFrame() Method to get the current frame object.
StateTable	getState() Method to get the shared partition variable.
Partition	getWork() Method to get the shared work variable.
void	initColls() This method initialises the number of collisions by setting it to 0.
void	initialize() Initialization of the mission.
long	missionMemorySize() Return the default memory size for a mission
void	recColls(int n) This method records a partial collisions result as it is generated by the detection handlers.
void	setFrame(RawFrame frame) Method to set the current frame object.
void	setState(StateTable state) Method to set the state of previous frame.
void	setWork(Partition work) Method to set the shared work variable.
