Missing info about how to get Vertex Label #2903

Closed Erhanjinn closed 3 years ago

Erhanjinn commented 4 years ago

Hello,

I wanted to use the isochrone resource, but I could not get it to work with Vertex labelas fromPlace.

At http://dev.opentripplanner.org/apidoc/1.4.0/resource_LIsochrone.html, there is no info about how to get such label. When I search my stop with http://localhost:8090/otp/routers/my_city/index/stops/1:112442 I get a valid result, but I am unable to contruct Vertex label out of it.

According to https://github.com/opentripplanner/OpenTripPlanner/blob/dev-1.x/src/main/java/org/opentripplanner/routing/graph/Vertex.java the label is an input parameter to the constructor, so I cannot really understand the way it is constructed.

Is it possible to compute Vertex label only knowing the GTFS files?

Thanks

Indeed the label is passed in when the Vertex is constructed. In the TransitStopVertex constructor, stop.getId().toString() is passed into the Vertex constructor as the label. The String representation of a stop ID is feedId + ID_SEPARATOR + id, so "feedId:stopId".
