Class uhr.core.role.StateCommandableAideStd 

java.lang.Object
   |
   +----uhr.core.role.StateCommandableAideStd
public class StateCommandableAideStd
extends Object
implements StateCommandableAide
This serves as an "aide-de-camp" to a StateCommandable. Its main responsibilities are:
1. Allow a parts commands to be easily listed in a context menu, made available when the user right clicks on the part in the System Tree.

2. House a resuable, stable state machine.

3. Increase the uniformity, understandablity and richness of state machine parts.

Please note that commands, states and transitions must be added in that order and no other.

Note this may be used by any class needing state assistance, but we speak as if it was used only by parts.
