[Insight-users] Memory Management

[Andreas Schuh]

Hi Michael,

yes, a smart pointer variable decreases the reference counter of the 
referenced object when it is destroyed, e.g. by leaving the scope it was 
declared in. If the reference counter of an object becomes zero, the 
object destroys itself.
But be aware of cyclic references. So if object A has a smart pointer 
member variable that references to object B and object B has a smart 
pointer variable that references to object A, neither of them will ever 
be destroyed, unless you force the release of one of them.

Andreas
