public class Dimensions
extends java.lang.Object

A Dimensions object represents the product or ratio of BaseUnits. The idea is that in order to add two Quantities (such as 3mm + 5cm) their Dimensions have to match. Equal dimensions are also ==.

Field Summary

static Dimensions

Empty The empty Dimensions that pure numbers have.

Method Summary

int	getPower(BaseUnit unit) Get the exponent for a BaseUnit in this Dimensions object.
int	hashCode()
static Dimensions	product(Dimensions a, int mul_a, Dimensions b, int mul_b)
java.lang.String	toString()
