Examples with Position aimax.osm.data.Position used on opensource projects

Example 1 with Position

use of aimax.osm.data.Position in project aima-java by aimacode.

the class RouteCalculator method calculateRoute.

/**
	 * Template method, responsible for shortest path generation between two map
	 * nodes. It searches for way nodes in the vicinity of the given nodes which
	 * comply with the specified way selection, searches for a suitable paths,
	 * and adds the paths as tracks to the provided <code>map</code>. Various
	 * factory methods can be used to override aspects of the default behavior
	 * in subclasses if needed.
	 * 
	 * @param markers
	 *            Nodes, not necessarily way nodes. The first node is used as
	 *            start, last node as finish, all others as via nodes.
	 * @param map
	 *            The information source.
	 * @param taskSelection
	 *            Number, indicating which kinds of ways are relevant.
