title: VTK Delete() and data deletion
body: <p>I was browsing through the VTK 5.4.2 code, and can't seem to understand how does the Delete() function works. I mean, the Delete() function is in vtkObjectBase and is virtual, but, through what chain of commands is the destructor of the vtkDoubleArray class (for example) executed?</p>
  
  <p>best regards,</p>
