Class: NavIndicator<T>

Defined in: workingtitle-instruments-wt21/shared/Navigation/NavIndicators/NavIndicators.ts:31

Represent a navigation indicator, like a course needle or bearing pointer. Can only be pointed to 1 nav source at a time. Gives visual components a single thing to subscribe to, while the actual source can be easily changed.
