Class MovableLocation

Direct Known Subclasses:

Car

public abstract class MovableLocation

extends Location

A location that can move. The state of movement is kept between height and destinationHeight. If they are equal, then the MovableLocation is still. If they are not equal, then the MovableLocation is moving. Valid states:

State	Variables	Transitions
	destinationHeight	setDestinationHeight()	[ArrivalEvent]
IDLE	height	IDLE:[arrive()] or travel(): MOVING	Impossible
MOVING	other	IDLE:[arrive()] or travel(): MOVING	IDLE:[arrive()]

Note that arrive() is like an event that is picked up by the subclass, as it is an abstract method.
