Your question has a simple response, make a test:
PRO test
o1 = OBJ_NEW('IDLgrImage')
o2 = OBJ_NEW('IDLgrImage')
o3 = OBJ_NEW('IDLgrImage')
o4 = OBJ_NEW('IDLgrImage')
c = OBJ_NEW('IDL_Container')
c->Add, [o1, o2, o3, o4]
print, 'Num object = ',c->Count()
HELP, /HEAP
OBJ_DESTROY, c
print, 'Container destroyed'
HELP, /HEAP
END
When you destroys an IDL_Container it executes the 'cleanup' method of
the holded objects.
Some is interesting destroy the container but not the objects inside it
(because another object has the same reference). Then is needes execute:
c->Remove, /ALL
OBJ_DESTROY, c
Bye.
PD: Take a look at my web page (this is not spam :) ) i have some litlle
clases for IDL that can simplify the OO programer life in IDL.
