内幕：UML与源代码
UML是一种设计语言，它的目的不是表现细节，而是表现结构，仅仅展示必要的细节。因此，UML不可能与源代码一一对应，只存在结构上的对应关系。作为一种参考，下面列出了图6-7中的类图的C#源代码：
interface IHuman
{
}
class Person : IHuman
{
void Read(Book book)
{
// …
}
}
class Author : Person
{
public Book[] books;
}
class Book
{
public Author author;
public Page[] pages;
}
class Page
{
}
class Bookshelf
{
public Book[] books;
}
{
}
class Person : IHuman
{
void Read(Book book)
{
// …
}
}
class Author : Person
{
public Book[] books;
}
class Book
{
public Author author;
public Page[] pages;
}
class Page
{
}
class Bookshelf
{
public Book[] books;
}
