register.java

某本RUP经典书籍的示例工程的部分代码实现,内含有一个Junit测试用例

package com.foo.nextgen.domain;

public class Register {
	private ProductCatalog catalog;
	private Sale currentSale;
	public Register(ProductCatalog catalog)
	{
		this.catalog = catalog;
	}
	public void endSale()
	{
		currentSale.becomeComplete();
	}
    public void enterItem(ItemID id,int quantity)
    {
    	ProductDescription desc = catalog.getProductDescription(id);
    	currentSale.makeLineItem(desc,quantity);
    }
    public void makeNewSale()
    {
    	currentSale = new Sale();
    }
    public void makePayment(Money cashTendered)
    {
    	currentSale.makePayment(cashTendered);
    }
}
