Examples with FlexStopLocation org.opentripplanner.model.FlexStopLocation used on opensource projects

Example 1 with FlexStopLocation

use of org.opentripplanner.model.FlexStopLocation in project OpenTripPlanner by opentripplanner.

the class NearbyStopFinder method findNearbyStopsViaStreets.

/**
 * Return all stops within a certain radius of the given vertex, using network distance along streets.
 * If the origin vertex is a StopVertex, the result will include it.
 *
 * @param originVertices the origin point of the street search
 * @param reverseDirection if true the paths returned instead originate at the nearby stops and have the
 *                         originVertex as the destination
 * @param removeTempEdges after creating a new routing request and routing context, remove all the temporary
 *                        edges that are part of that context. NOTE: this will remove _all_ temporary edges
 *                        coming out of the origin and destination vertices, including those in any other
 *                        RoutingContext referencing them, making routing from/to them totally impossible.
 *                        This is a stopgap solution until we rethink the lifecycle of RoutingContext.
