[Gambas-user] Do embeded objects get released too upon destruction ?

[nando]

Ok, so the following line...

  DIM Q AS NEW myClass[5]

would need...

  FOR i = 0 TO 4
    myClass[i] = NEW myClass
  NEXT


to instantiate each myClass object.

The _init would then execute creating the string objects

Does this line...

  myClass[5] = NULL

do a deep unreference to the embedded strings too?
