Represents an primitive \fBNull\fP value. 

All instances of this class share the same implementation object, so == will always return true for any comparison between two \fBNull\fP objects.

.PP
Converts a \fBValue\fP into an \fBNull\fP. If the value's type is not NullType, a null object will be returned (i.e. one with it's internal pointer set to 0). If you do not know for sure whether the value is of type NullType, you should check the \fBisNull\fP() methods afterwards before calling any methods on the returned value.
