Base class from providing referencing counted objects

Inheritance:

Public Methods

Referenced()

Referenced(const Referenced&)

inline Referenced& operator = (Referenced&)

inline void ref() const

increment the reference count by one, indicating that this object has another pointer which is referencing it

inline void unref() const

decrement the reference count by one, indicating that a pointer to this object is referencing it.

inline void unref_nodelete() const

decrement the reference count by one, indicating that a pointer to this object is referencing it.

inline const int referenceCount() const

return the number pointers currently referencing this object.

Base class from providing referencing counted objects

Referenced()

Referenced(const Referenced&)

inline Referenced& operator = (Referenced&)

inline void ref() const

increment the reference count by one, indicating that this object has another pointer which is referencing it

inline void unref() const

decrement the reference count by one, indicating that a pointer to this object is referencing it. If the reference count goes to zero, it is assumed that this object is no longer referenced and is automatically deleted.

inline void unref_nodelete() const

decrement the reference count by one, indicating that a pointer to this object is referencing it. However, do not delete it, even if ref count goes to 0. Warning, unref_nodelete() should only be called if the user knows exactly who will be resonsible for, one should prefer unref() over unref_nodelete() as the later can lead to memory leaks.

inline const int referenceCount() const

return the number pointers currently referencing this object.

virtual ~Referenced()

mutable int _refCount
