面向对象设计 : Car - Connection between Tank and Engine

Question

我不确定我是否疯狂地违反了 OOP 概念。
说有一个 Car “ 具有 ”和 Engine 的类和一个 Tank .
当Engine正在运行，它将从 Tank 取油(尽管油是不可数的，但每个周期一个单位说一个单位)Engine应该怎么做从 Tank 获取石油? (当两者都是 Car 的字段时？)

实际上是 Engine应该不断地“供应”油而不是
比“得到”石油。应该有"OilCirculatingSystem"从 Tank 获取石油
并供应给 Engine .如何在类里面为这个系统建模？
有没有合适的设计模式？


** * 编辑:简单地说，如何从 Tank 获得“油流”至 Engine ? (当阀门打开时，Oil 是否有责任从 Tank 流向 Engine？

Answer 1

对不起，如果它炸了大脑。缺少方法的实现，但你得到了我希望的想法。

class Tank
{
    Oil oil;

    public Tank(OilPipe pipe)
    {
        pipe.OilNeeded += new EventHandler<OilNeededEventArgs>(pipe_OilNeeded);
    }

    public void FillOil(Oil oil) { }

    void pipe_OilNeeded(object sender, OilNeededEventArgs e)
    {
        e.Oil = oil.SubtractLiters(5);
    }
}

class OilPipe
{
    public event EventHandler<OilNeededEventArgs> OilNeeded;

    public Oil SuckOil();
}

class Piston
{
    public void Move() { }
}

class Oil
{
    public Energy Burn() { }
}

class Energy
{
    public void Push(Piston piston) { }
}

class Engine
{
    OilPipe oilPipe;

    public Engine(OilPipe oilPipe, Piston piston)
    {
        this.oilPipe = oilPipe;
    }

    public void MovePiston()
    {
        Oil oil = oilPipe.SuckOil();
        Energy energy = Burn(oil);
        energy.Push(piston);
    }
}

class Car
{
    Engine engine;

    public Car(Engine engine, Tank tank)
    {

    }

    public void Accelerate()
    {            
         engine.MovePiston();
    }
}
