Declaration
public static Nullable<Point> FindDuplicate(IEnumerable<Point> source)
Parameters
System.Collections.Generic.IEnumerable<System.Windows.Point> source

The source.
Returns
System.Nullable<System.Windows.Point>

GetRoutePoints(IConnection, Boolean)

Gets the route points.

Declaration
public override IList<Point> GetRoutePoints(IConnection connection, bool showLastLine = true)
Parameters
IConnection connection

The connection.
System.Boolean showLastLine

If set to true the intermediate points will be added to the resulting path.
Returns
System.Collections.Generic.IList<System.Windows.Point>

Overrides

RemoveLoops(IList<Point>)

Removes the loops in the point list.

Declaration
public static IList<Point> RemoveLoops(IList<Point> points)
Parameters
System.Collections.Generic.IList<System.Windows.Point> points

The points.
Returns
System.Collections.Generic.IList<System.Windows.Point>

Route(Point, Point)

Returns null, if no path is found. Start- and End-Node are included in returned path.
