Detailed Description

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.

Constructor & Destructor Documentation

KSharedPtr::KSharedPtr ( ) [inline]

Creates a null pointer.

Definition at line 106 of file ksharedptr.h.

KSharedPtr::KSharedPtr ( T *  t) [inline]

Creates a new pointer.

Parameters:
tthe pointer

Definition at line 112 of file ksharedptr.h.

KSharedPtr::KSharedPtr ( const KSharedPtr p) [inline]

Copies a pointer.

Parameters:
pthe pointer to copy
