将内联函数从标题移动到源

Question

我是C++的新手,所以我提前为我的问题的世俗性质道歉.

我被要求将以下内联函数从头文件移动到源文件.但是我很难在源文件中获得正确的语法.这是头文件中的内联函数:

class G1FRViewOption
 {
    public:
        enum ViewType {partyView, contraView, unknown} ;
        G1FRViewOption() : m_view     (nullString )
                     , m_viewType (unknown    )
                     , m_isValid  (false      ) {initialise();} 
        G1FRViewOption(const RWCString view) : m_view     (view    )
                                         , m_viewType (unknown )
                                         , m_isValid  (false   ) {initialise();}
        void initialise()
        {
            static RWCString views[] = {"party","contra"} ;
            for (int vt=counterpartyView; vt<unknown; vt++)
                if (m_view.compareTo(views[vt], RWCString::ignoreCase)==0)
                {
                    m_viewType  = (ViewType) vt ;
                    m_isValid   = true          ;
                    break ;
                }
        } 
        RWCString getErrorMessage()
        {
            return "Invalid " + getFieldLabel() + " given. Valid values are party, contra.";
        }
        G1FRViewOption & operator = (const G1FRViewOption & other)
        {
            this->m_view     = other.m_view     ;
            this->m_viewType = other.m_viewType ;
            this->m_isValid  = other.m_isValid  ;
            return *this ;
        } 
              RWBoolean   is        (ViewType viewType) const {return viewType == m_viewType ;} 
              RWBoolean   isValid   () const {return m_isValid ;} 
        const RWCString & toString  ()       {return m_view    ;} 
        static const RWCString       & getFieldLabel         () { static RWCString value = "View"         ; return value ; } 
        static const FieldDefinition & getFieldDefinition    () { static const FieldDefinition fd (getFieldLabel(), 13) ; return fd ; } 
    private:
        RWCString m_view     ;
        ViewType  m_viewType ;
        RWBoolean m_isValid  ;} ;

任何帮助将不胜感激.

提前谢谢了.

将函数从标题中移出到cpp文件中,首先创建相应的cpp文件(如果它不存在),然后将函数的主体逐个复制到该文件中,在其名称前加上类的名称和两个冒号::,像这样:

void initialise()
{
    static RWCString views[] = {"party","contra"} ;
    for (int vt=counterpartyView; vt<unknown; vt++)
        if (m_view.compareTo(views[vt], RWCString::ignoreCase)==0)
        {
            m_viewType  = (ViewType) vt ;
            m_isValid   = true          ;
            break ;
        }
}

从标题变成

void initialise();

在标题中,和

void G1FRViewOption::initialise()
{
    static RWCString views[] = {"party","contra"} ;
    for (int vt=counterpartyView; vt<unknown; vt++)
        if (m_view.compareTo(views[vt], RWCString::ignoreCase)==0)
        {
            m_viewType  = (ViewType) vt ;
            m_isValid   = true          ;
            break ;
        }
}

在cpp文件中.
