经典书籍源代码啊。。。第三版。。。数据结构与算法分析——C++描述(第3版).

// Example of an Employee class
class Employee
{
  public:
    const string & getName( ) const
      { return name; }

    bool operator==( const Employee & rhs ) const
      { return getName( ) == rhs.getName( ); }
    bool operator!=( const Employee & rhs ) const
      { return !( *this == rhs; }

      // Additional public members not shown

  private:
    string name;
    double salary;
    int    seniority;

      // Additional private members not shown
};

int hash( const Employee & item )
{
    return hash( item.getName( ) );
}
