Detailed Description
template<class T>
class KSharedPtr< T >
Can be used to control the lifetime of an object that has derived KShared.
As long a someone holds a KSharedPtr on some KShared object it won't become deleted but is deleted once its reference count is 0. This struct emulates C++ pointers virtually perfectly. So just use it like a simple C++ pointer.
KShared and KSharedPtr are preferred over QShared / QSharedPtr since they are more safe.
WARNING: Please note that this class template provides an implicit conversion to T*. Do *not* change this pointer or the pointee (don't call delete on it, for instance) behind KSharedPtr's back.

KSharedPtr< T >::KSharedPtr | ( | ) | [inline] |
Creates a null pointer.

KSharedPtr< T >::KSharedPtr | ( | T * | t | ) | [inline] |
KSharedPtr< T >::KSharedPtr | ( | const KSharedPtr< T > & | p | ) | [inline] |
KSharedPtr< T >::~KSharedPtr | ( | ) | [inline] |
Unreferences the object that this pointer points to.
If it was the last reference, the object will be deleted.
