Class PersonMovementFix

java.lang.Object
  movements.PersonMovement
      movements.PersonMovementFix

All Implemented Interfaces:

java.io.Serializable

class PersonMovementFix

extends PersonMovement

This class implements a movement of a participant that is in fact a movement over a time period of zero length. It basically fixes a person to a point at a specific time.

This type of movement is used with transition processing, because transitions are carried out to connect two otherwise disjointed movements together. A transition may occur entirely before or entirely after the transition point. If there is otherwise no movement on the other side of the transition then we need a movement that lasts zero bars.

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.
