Interface IRandomizer

All Known Implementing Classes:

Randomizer

public interface IRandomizer

A utility class used to generate different types of random values.

Method Summary

Rectangle	randomBounds(Rectangle rect, Dimension maxDim) Generates a randomly located and sized rectangle
Object	randomChoice(Object x, Object y, double probX) Returns a random choice of one of two objects, x and y, where probX is the probability that x will be picked (0<=x<=1).
Color	randomColor() Generates a random color
Dimension	randomDim(Dimension maxDim) Returns a random square Dimension, whose width is maxDim.width/2<=width<=maxDim.width
double	randomDouble(double min, double max) Returns a random double greater than or equal to min and less than or equal to max.
int	randomInt(int min, int max) Returns a random integer greater than or equal to min and less than or equal to max.
Point	randomLoc(Dimension dim) Generates a random location point subject to the constraint that 0<=X<=maxX and 0<=Y<=maxY.
Point	randomLoc(Rectangle rect) Generates a random location point subject to the constraint that 0<=X<=maxX and 0<=Y<=maxY.
Point	randomVel(Rectangle rect) Returns a random velocity (as a Point) subject to the constraint that the absolute value of the vleocity (speed) is less than maxV.

Method Detail

randomInt

int randomInt(int min,
              int max)

Returns a random integer greater than or equal to min and less than or equal to max.

randomDouble

double randomDouble(double min,
