\subsection{Detailed Description}
Represents an primitive {\bf Undefined}{\rm (p.\,\pageref{classKJS_1_1Undefined})} value. 

All instances of this class share the same implementation object, so == will always return true for any comparison between two {\bf Undefined}{\rm (p.\,\pageref{classKJS_1_1Undefined})} objects.

Converts a {\bf Value}{\rm (p.\,\pageref{classKJS_1_1Value})} into an {\bf Undefined}{\rm (p.\,\pageref{classKJS_1_1Undefined})}. 

If the value's type is not Undefined\-Type, 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 Undefined\-Type, you should check the {\bf is\-Null}{\rm (p.\,\pageref{classKJS_1_1Value_a6})}() methods afterwards before calling any methods on the returned value.

\item[Returns:]The value converted to an {\bf Undefined}{\rm (p.\,\pageref{classKJS_1_1Undefined})} \end{Desc}
