Class PersonMovementAlone

java.lang.Object
  movements.PersonMovement
      movements.PersonMovementAlone

All Implemented Interfaces:

java.io.Serializable

class PersonMovementAlone

extends PersonMovement

This class implements a movement of a person over a period of time. A person's position is defined using three co-ordinates giving the distance down the set, the distance across the set, and the direction in which the person is facing. This class contains three instances of SingleDimensionalMovement which give the position of the person and the direction that the person is facing at any point of time during the movement.

Field Summary

private SingleDimensionalMovement	movementAcross
private SingleDimensionalMovement	movementDirection
private SingleDimensionalMovement	movementDown
protected int	tickLength

Constructor Detail

PersonMovementAlone

PersonMovementAlone(int tickLength,
                    SingleDimensionalMovement movementDown,
                    SingleDimensionalMovement movementAcross,
                    SingleDimensionalMovement movementDirection)

Method Detail

getPosition

void getPosition(ParticipantPosition position,
                 int ticksIntoMovement)

Specified by:

getPosition in class PersonMovement

Trace

public void Trace(java.lang.String indent)

Overrides:

Trace in class PersonMovement

getTickLength

int getTickLength()

getPosition

ParticipantPosition getPosition(int ticksIntoMovement)

splitMovement

final PersonMovement splitMovement(int subPeriodStartTick,
                                   int subPeriodEndTick)

Provides a movement that covers only a period of this movement. This method does some error checking and handles the request in a couple of trivial situations. It calls an implementation specific method to handle the non-trivial cases.

splitMovementInternal

protected PersonMovement splitMovementInternal(int subPeriodStartTick,
                                               int subPeriodEndTick)

Provides a movement that covers only a period of this movement. This is a default implementation that uses the PersonMovementSplitter to provide the desired sub-movement. However, most implementations of PersonMovement can do this more efficiently and so override this method. By allowing each PersonMovement implementation to implement this, we get a simpler tree of PersonMovement objects.
