Class SingleDimensionalMovement

java.lang.Object
  movements.SingleDimensionalMovement

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

PolynomialMovement, SinusoidalMovement, StationaryMovement

abstract class SingleDimensionalMovement

extends java.lang.Object

implements java.io.Serializable

An object of this class represents a movement in a single dimension over a period of time.

Objects of this class are used, for example, to represent the movement of a person or the movement of a person's hand. The movement of a person would require three objects of this class, one to indicate the distance down the set, one to indicate the distance across the set and one to represent the direction in which the person is facing. The movement of a hand, however, would require only two objects of this class.

This class is abstract. Classes are derived from this class that implement various movements. For example, a derived class may implement a linear movement and another derived class may implement a sinusoidal movement.

GetPosition

abstract double GetPosition(int ticksIntoMovement)

Given a point of time as the number of 'ticks' after the start of the movement, this method returns the position at that point of time. If the 'tick' parameter is less than zero or is greater than the number of ticks in the movement then the result of this method is undefined.
