QuantityDimension (VisAD 2.0.0-scijava-2-SNAPSHOT API)

java.lang.Object
- visad.QuantityDimension

All Implemented Interfaces:

Serializable, Comparable
```
public final class QuantityDimension
extends Object
implements Serializable, Comparable
```
This class represents the dimension of a quantity. For example, consider a nonrelativistic particle of mass m in uniform motion which travels a distance l in a time t. Its velocity is v=l/t and its kinetic energy is E=mv²/2=ml²t^-2/2. The dimension of E is dim E=ML²T^-2 and the dimensional exponents are 1, 2, and -2. A QuantityDimension is immutable.
