Class Quantity

java.lang.Object
  net.commerce.zocalo.currency.Quantity

All Implemented Interfaces:

java.lang.Comparable

Direct Known Subclasses:

RangedQuantity

public class Quantity
extends java.lang.Object
implements java.lang.Comparable

Quantities represent numbers using BigDecimal. They carry a MathContext for computations. Subclasses represent Price and Probability by limiting the range of possible values and being able to scale.
