Public Function elements () As Integer

Remarks
The following example packs the contents of a set into a container. The elements method is used to test whether the set has any contents. If there are no contents, a nullNothingnullptrunita null reference (Nothing in Visual Basic) container is returned.
public static container intSet2Con(Set _intSet)
{
SetEnumerator se;
container intCon;
;
if (!_intSet || !_intSet.elements())
{
return conNull();
}
se = _intSet.getEnumerator();
while (se.moveNext())
{
intCon += se.current();
}
return intCon;
}
