[Insight-developers] itkCellInterface

[Miller, James V (Research)]

One thing that the code is doing is skipping the object factory. But it also has
a difference from the NewMacro() wrt the reference count.  Objects created with 
the NewMacro start with a reference count of 1 on construction.  The count
rises to 2 when the pointer is assigned to the smartpointer to be returned.
Then it is decreased down to 1 before it leaves the macro.

Can you run a quick test?  Create an instance and assign it to a SmartPointer.
Then print out the reference count on the object.  I suspect that the reference
count will be 2. Which is one too high.

Hi everyone,

I am just wondering why the following line on itkCellInterface.h (line
182)is replaced, it makes me a bit unclear about garbage collection and
hence leaks

 //itkNewMacro(Self);
 static  Pointer New(void) { return new Self; }



Thanks


Leila
