When you modify a state of type a by setting a property of type b, or by
changing something that it's not the "whole" state, you get an example
of a write-only property. 

This is not the only way to model the... thing. 

Consider a progress bar or a volume control, where you can increment the
value by a relative amount. This is a write-only property, but only if
you want to model the interface of a relative increase by a property.
There might be better ways.
