## Detailed Description

### template<class T>
struct 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 perfectly. So just use it like a simple C++ pointer.

KShared and KSharedPtr are preferred over QShared / QSharedPtr since they are more safe.

## Constructor & Destructor Documentation

template<class T>
KSharedPtr< T >::KSharedPtr | ( |  | ) | `[inline]`

| Creates a null pointer. Definition at line 102 of file ksharedptr.h.

template<class T>
KSharedPtr< T >::KSharedPtr | ( | T * | t | ) | `[inline]`

  | Creates a new pointer. Parameters:
  the | pointer
Definition at line 108 of file ksharedptr.h.

template<class T>
KSharedPtr< T >::KSharedPtr | ( | const KSharedPtr< T > & | p | ) | `[inline]`

  | Copies a pointer. Parameters:
  the | pointer to copy
Definition at line 115 of file ksharedptr.h.

template<class T>
KSharedPtr< T >::~KSharedPtr | ( |  | ) | `[inline]`

| Unreferences the object that this pointer points to. If it was the last reference, the object will be deleted. Definition at line 122 of file ksharedptr.h.
