GetODRefCntObjectDestructor

Retrieves a destructor for a reference-counted object.

ParamDestructorUPP GetODRefCntObjectDestructor ();

return value

A pointer to a destructor function that takes two parameters: an environment pointer and a pointer of type ODRefCntObject*; the function returns no value. The function has the following form:

void ODRefCntObjectDestructor (Environment* ev,
ODRefCntObject* refCntObj);

DISCUSSION

You call this method to retrieve a destructor function suitable for an ODRefCntObject object. The destructor function releases the object, as shown in the following example:

ODRefCntObjectDestructor (Environment* ev, ODRefCntObject* refCntObj)
{
   refCntObj->Release(ev);
}

If you subclass ParameterSet, do not override this method.
