public class ShortAddrVariableValue
extends DecVariableValue

Representation of a short address (CV1).

This is a decimal value, extended to modify the other CVs when written. The CVs to be modified and their new values are stored in two arrays for simplicity.

The NMRA has decided that writing CV1 causes other CVs to update within the decoder (CV19 for consisting, CV29 for short/long address). We want DP to overwrite those _after_ writing CV1, so that the DP values are forced to be the correct ones.
