public interface LazyCalc<T>
extends CalcValue<T>

Interface for calculations with a dirty and setup concept.

Method Summary

boolean	isDirty() When dirty is false that means that the calculated value can be used
void	setup() Currently not super well define used for 2 purposes: Reset: called from the outside if you want to reuse it init: Called from the inside when calculation start to have everything setup maybe the semantic could work for both? TODO: This should be separated better.
