public interface Scalar

Basic type definition for all scalar types. getValue() never returns null, even if the channel never connected. One must always look at the alarm severity to be able to correctly interpret the value.

As of 1.1, this class is not a generic type. This is due to a bug in 1.6 compiler where generic return type clash with covariant return types.
