Method Detail

setFeature

public void setFeature(Feature feature)

Description copied from interface: IDistance

Sets the current feature

Specified by:

setFeature in interface IDistance

getInInternalUnits

protected double getInInternalUnits(double userEntryDistance,
                                    IProjection proj,
                                    int distanceUnits,
                                    int mapUnits)

Converts a distance entered by user in the GUI in the same distance in internal units (measure units)

setNumberOfRings

public void setNumberOfRings(int n)

Description copied from interface: IDistance

Sets the number of rings. This number is multiplied by the Buffer distance. For instance, for a constant distance of 500 meters and two rings, the getBufferDistance will give a value of 1000
