Class PruneFloatingIslands

java.lang.Object

org.opentripplanner.graph_builder.module.PruneFloatingIslands

All Implemented Interfaces:

GraphBuilderModule

public class PruneFloatingIslands
extends Object
implements GraphBuilderModule

this module is part of the GraphBuilderModule process. it design to remove small isolated islands form the graph. Islands are created when there is no connectivity in the map, island acts like trap since there is no connectivity there is no way in or out the island. The module distinguish between two island types one with transit stops and one without stops.
