The OBJ_DESTROY procedure is used to destroy an object. If the class (or one of its superclasses) supplies a procedure method named CLEANUP, the method is called and all arguments and keywords passed by the user are passed to it. This method should perform any required cleanup on the object and return. Whether a CLEANUP method actually exists or not, IDL will destroy the heap variable representing the object and return.
Note that OBJ_DESTORY does not recurse. That is, if
object1
contains a reference to
object2
, destroying
object1
will
not
destroy
object2
. Take care not to lose the only reference to an object by destroying an object that contains that reference. Recursive cleanup of object hierarchies is a good job for a CLEANUP method.
