Constructor |

The default value - the value that will be returned if none has been explicitly set. Overwrite this method with the class specific default value. |
|
Return whether or not the value is defined, i.e. whether or not a value has been set before. |
|
Set the value. |
|
Invalidate the value, i.e. make it undefined - just like at object creation time. |
