Convenient pointer for objects of Cocos2d-x

cocos2d-x C++
1

Hi,

I wrote tool for working with pointers on Cocos2d-x objects.

#ifndef CCPtr_h
#define CCPtr_h

#include <type_traits>
#include "cocos2d.h"

template < class T,
           class = typename std::enable_if<std::is_base_of<cocos2d::Ref, T>::value>::type
>

class CCPtr {
    cocos2d::Ref *m_ptr = nullptr;
public:
    CCPtr() {}
    
    CCPtr(T *obj) {
        if (m_ptr) {
            m_ptr->release();
        }
        m_ptr = obj;
        m_ptr->retain();
    }
    
    CCPtr(CCPtr<T> &obj) {
        if (m_ptr) {
            m_ptr->release();
        }
        m_ptr = obj.m_ptr;
        m_ptr->retain();
    }
    
    CCPtr(CCPtr<T>&& obj) {
        m_ptr = obj.m_ptr;
        obj.m_ptr = nullptr;
    }
    
    void operator=(T *obj) {
        if (m_ptr) {
            m_ptr->release();
        }
        m_ptr = obj;
        m_ptr->retain();
    }
    
    void operator=(CCPtr<T> &obj) {
        if (m_ptr) {
            m_ptr->release();
        }
        m_ptr = obj.m_ptr;
        m_ptr->retain();
    }
    
    void operator=(CCPtr<T>&& obj) {
        m_ptr = obj.m_ptr;
        obj.m_ptr = nullptr;
    }

    ~CCPtr() {
        if (m_ptr) {
            m_ptr->release();
        }
        m_ptr = nullptr;
    }
    
    T* get () const { return static_cast<T*>(m_ptr); }
    T* operator->() const { return static_cast<T*>(m_ptr); }
};


#endif /* CCPtr_h */

You no longer have to take care of the call retain() and release().
What do you think about it?

Oh. The cocos already has this class. Fail!
