[Insight-users] force to destroy object

[Ivan Macia]

Hi Samuele, Dan,

In order to force decreasing the reference count I usually do:

myptr = 0;

where myptr is obviously and smart pointer. This is very useful specially
with smart pointer class members, in order to release memory when we don't
need it (at least locally) and the class instance is still persistent. The
object will delete itself only when it is not referenced elsewhere. We do
this in our programs and works perfectly.

Regards

Iván
