createprueflat.hxx

手柄类 我跟着钱能的书写的 不过收获了不少

#include "createsony.hxx"
#include "a29.hxx"


#ifndef headr_create
#define headr_create
class pureflatcreate:public createsony
{
public:
    sony * createinch29(){return new a29();}
	sony * createinch43(){return new a43();}
};


class plasmacreate:public createsony
{
public:
    sony * createinch29(){return new b29();}
	sony * createinch43(){return new b43();}
};



class liquidcrystalcreate:public createsony
{
public:
    sony * createinch29(){return new c29();}
	sony * createinch43(){return new c43();}
};

#endif
//为什么不能再此定义
//因为一个头文件的实现可以在本头文件中，或在一个cpp文件中不能在另一个头文件
//createsony * createpureflat(){return new pureflatcreate();}
//createsony * createplasma(){return new plasmacreate();}
//createsony * createliquidcrystal(){return new liquidcrystalcreate();}
