Detailed Description

An abstract class for reference counting.

Each class, which needs reference counting, must be a descendant of this class (or must implement it by itself). It was mainly created to be used by ListItem class in list and hashtable implementations.

Note: there is a big difference between this implementation and usual ones. When reference count of the object decreases to zero, it is not destroyed. Special destroy() method must be called.

void RefCount::addRef (    )  [inline]

Reference count incrementation. This method increments number of references. See also: releaseRef() Definition at line 75 of file refCount.h. Referenced by ListItem::add().

virtual void RefCount::destroy (    )  [inline, virtual]
