整个函数非常棒(来自Linux的sunhme.c驱动程序，用于被Sun戏称为“快乐套餐”的网卡)。因为在那之前的卡片是“巨无霸”。明白了吗?明白了吗?)

static void happy_meal_tcvr_write(struct happy_meal *hp,
                              void __iomem *tregs, int reg,
                              unsigned short value)
{
    int tries = TCVR_WRITE_TRIES;

    ASD(("happy_meal_tcvr_write: reg=0x%02x value=%04x\n", reg, value));

    /* Welcome to Sun Microsystems, can I take your order please? */
    if (!(hp->happy_flags & HFLAG_FENABLE)) {
            happy_meal_bb_write(hp, tregs, reg, value);
            return;
    }

    /* Would you like fries with that? */
    hme_write32(hp, tregs + TCVR_FRAME,
                (FRAME_WRITE | (hp->paddr << 23) |
                 ((reg & 0xff) << 18) | (value & 0xffff)));
    while (!(hme_read32(hp, tregs + TCVR_FRAME) & 0x10000) && --tries)
            udelay(20);

    /* Anything else? */
    if (!tries)
            printk(KERN_ERR "happy meal: Aieee, transceiver MIF write bolixed\n");

    /* Fifty-two cents is your change, have a nice day. */

}

这实际上是我在实现原型转换为实际代码时所做的:

// Abandon all hope you who needs to debug this

是的，有比我聪明的人在之后重构了代码(它必须有一个好的结局)。

在一个名为“Bar”的类中(这是一个不具有描述性名称的UI控件)，类头文件:

/// <summary>I pity the "foo".</summary>

Remove()方法:

/// <summary>A "foo" and his money are soon parted.</summary>

更糟糕的是，业务合作伙伴从生成的文档中指出了这一点。更糟糕的是，这些可能是我们从那家伙那里得到的最接近有用文件的东西。

这是我曾经必须支持的实际代码。在努力理解AstaSaysGooGoo和AstaSaysGaaGaa(在那里有更多的astaTempVars被声明和使用)的逻辑之后，我准备放弃。我终于抬头看到了“@author”的评论，整件事开始有意义了。

/*

* @author Andrew Asta
*/
public class AstaClass{

    private String astaVar1;    
    private String astaVar2;    
    private String astaVar3;    
    private String astaVar4;    
    private String astaVar5;    
    private String astaVar6;    
    private String astaVar7;    
    private String astaVar8;    
    private String astaVar9;    
    private String astaVar10;   

    public void AstaSaysGetData(){
        //JDBC statement to populate astavars 1 through 10
        //...
        String astaSqlStatment = "Select astaCol1, astaCol2, astaCol3... From AstaTable Where...";
        //..
        //...
    }

    //Perform data manipulation on astavars...
    public void AstaSaysGaaGaa(){
          [removed for sake of brevity]
    }


    //Perform more data manipulation on astavars...
    public void AstaSaysGooGoO(){
        [removed for sake of brevity]
    }

    public void AstaSaysPersist(){      
        //JDBC statement to save astavars to DB 
        String astaSqlStatment = "Update AstaTable set astaCol1 = @astaVar1
                                                  , set astaCol2 = @astaVar2
                                                  , set astaCol3 = astaCol3... 
                                                  Where...";
    }
}

另外，我更改了实际作者的真实姓名，以避免我陷入任何纠纷等等…

// This code sucks.
