"传统的"C++类(只是一些随机声明)可能类似于以下内容:

class Foo
{
public:
  Foo();
  explicit Foo(const std::string&);
  ~Foo();

  enum FooState
  {
    Idle, Busy, Unknown
  };

  FooState GetState() const;
  bool GetBar() const;
  void SetBaz(int);

private:
  struct FooPartialImpl;

  void HelperFunction1();
  void HelperFunction2();
  void HelperFunction3();

  FooPartialImpl* m_impl; // smart ptr
  FooState m_state;
  bool m_bar;
  int m_baz;
};

如果原始程序员没有整齐地组织他的"访问区域",我总是发现这种类型的访问级别规范很难并且难以遵循.

看一下Java/C#风格的相同代码片段,我们得到:

class Foo
{
  public: Foo();
  public: explicit Foo(const std::string&);
  public: ~Foo();

  public: enum FooState
  {
    Idle, Busy, Unknown
  };

  public: FooState GetState() const;
  public: bool GetBar() const;
  public: void SetBaz(int);

  private: struct …
