[Design Pattern] The abstract factory pattern example

아래는 추상 팩토리 패턴의 예제로 C 스타일의 예제가 없어서 만들어 봤다.

 

class CDBProcess
{
public:
 virtual void LoadCharacter() = 0;
};

class CSDBProcess : public CDBProcess
{
 void LoadCharacter()
 {
  printf("SDB\n");
 }
};

class CXDBProcess : public CDBProcess
{
 void LoadCharacter()
 {
  printf("XDB\n");
 }
};

class CDBProcessFac 
{
public:
 virtual CDBProcess* CreateProcess() = 0;
};

class CXDBProcessFac : public CDBProcessFac
{
 CDBProcess* CreateProcess()
 {
  return new CXDBProcess;
 }
};

class CSDBProcessFac : public CDBProcessFac
{
 CDBProcess* CreateProcess()
 {
  return new CSDBProcess;
 }
};

void main() 
{
 CDBProcessFac *pCDBProcessFac = new CSDBProcessFac;
 CDBProcess    *pCDBProcess = pCDBProcessFac->CreateProcess();

 pCDBProcess->LoadCharacter();
 

}
