Class RealFunctionPeriodicOnIntegers

java.lang.Object

de.jtem.function.real.RealFunctionPeriodicOnIntegers

All Implemented Interfaces:

public class RealFunctionPeriodicOnIntegers
extends Object
implements RealFunction.PeriodicOnIntegers

An implementation of the interface IntegerFunction.PeriodicOnIntegers. Function values are stored internally, so using this class to make a copy of a RealFunction.PeriodicOnIntegers c (by the corresponding constructor or the assign method) will make a snapshot of the current state of c. No reference to c itself is retained.

Constructor Summary

Constructors

Constructor and Description
RealFunctionPeriodicOnIntegers()
RealFunctionPeriodicOnIntegers(int n) Creates a periodic sequence of period n with all values equal to zero.
RealFunctionPeriodicOnIntegers(RealFunction.PeriodicOnIntegers c) Creates a copy of c.

Method Summary

Modifier and Type	Method and Description
void	assign(RealFunction.OnIndex c) Become the periodic extension of c.
void	assign(RealFunction.PeriodicOnIntegers c) Become a copy of c.
void	assignZero() Keep the period but set all values to zero.
void	assignZero(int n) Become a periodic sequence of period n with all values equal to zero.
int	getPeriod() Returns the period of this function (a positive integer), refering to the behaviour in the last coordinate.
void	setPeriod(int n) Do nothing if n is equal to the current period, become a periodic sequence with period code>n and all values zero otherwise.
void	setValueAt(int j, double x)
double	valueAt(int j) returns the value of this function at j.
