NrroImageSP Class Reference

#include <nrroImage.h>

Inheritance diagram for NrroImageSP:

gutz::SmartPtr< NrroImage > gutz::Counted List of all members.

Detailed Description

the smart pointer, a new class just so we can do automatic casts to the parent class "Nrro"

Definition at line 86 of file nrroImage.h.

You don't need this for an "up-cast" since this thing automatically casts itself to a pointer which will then be up-casted by the compiler.

bool operator! () const
bool isNull () const
 just for convienence.


Protected Member Functions

void assign (NrroImage *const ref)
virtual void _incCount ()
 gutz::Counted interface, increment reference count by one.

virtual void _decCount ()
 gutz::Counted interface, decrement reference count by one.

virtual int _getCount () const
 gutz::Counted interface, get the current reference count.


Protected Attributes

NrroImage * _ref
 The only data we have is this pointer, so we have the same memory foot print of a regular pointer.

void gutz::SmartPtr< NrroImage >::assign (  NrroImage *const  ref  )  [inline, protected, inherited]
 

inc ref if non-zero

save off old reference

assign _ref = ref

delete the old reference

just a dec most of the time...

but if we hold the last reference, nuke it
