Can be used to control the lifetime of an object that has derived QSharedData.
KSharedPtr< T > & operator=(const KSharedPtr &o)
~KSharedPtr()
Unreferences the object that this pointer points to.
const T * constData() const
void clear()
Clear the pointer, i.e.
bool operator<(const KSharedPtr &o) const
static KSharedPtr< T > dynamicCast(const KSharedPtr< U > &o)
Convert KSharedPtr<U> to KSharedPtr<T>, using a dynamic_cast.
int count() const
Returns the number of references.
bool isNull() const
Test if the shared pointer is null.
KSharedPtr()
Creates a null pointer.
void attach(T *p)
Attach the given pointer to the current KSharedPtr.
const T * operator->() const
bool operator!=(const KSharedPtr &o) const
static KSharedPtr< T > staticCast(const KSharedPtr< U > &o)
Convert KSharedPtr<U> to KSharedPtr<T>, using a static_cast.
KSharedPtr(T *p)
Creates a new pointer.
bool operator==(const KSharedPtr &o) const
const T & operator*() const
KSharedPtr(const KSharedPtr &o)
Copies a pointer.
