How to model barriers?

[patrickarlt]

In a closer reading of the routing API it looks like barriers can also have some attributes that control things like adding travel time/distance or prohibiting travel through a barrier altogether.

It looks like there are 3 kinds of barriers

• Point - add time/distance OR prohibit travel along the street or through the point
• Line - prohibits travel through the line
• Polygon - add time/distance OR prohibit travel along the street or through the polygon

My question is should be model these as 3 distinct classes with concrete methods like addTravelTime(2, 'Miles')?

• L.esri.Routing.Barriers.Point
• L.esri.Routing.Barriers.Polyline
• L.esri.Routing.Barriers.Point

or should we only allow simple barrier (GeoJSON) that prohibit travel and call it a day?

using barriers to tack on a time/distance penalty is much less common than complete prohibition so i think implementing simple barriers in the intial release would be entirely sufficient.
