适配器模式

/***********************************************************
 * 适配器模式 (参照李会军老师的ˇ〃ˇ)
 *描述:
 *如下代码所示, 原接口IMyInterFace函数Write在己开发完成的代码中大量的用到,
 * 但由于业务有变,而要通过IMyInterFace接口调用WriteFactory函数,
 * 如果大批量的将Write修改成WriteFactory的话,工作量是疯狂的.
 * 这时,适配器模式就有他的优势了

/***********************************************************
 * "适配器模式" 和"抽象工厂模式"似乎异曲同工
