Interface IDistance

All Known Implementing Classes:

AbstractDistance, ConstantDistance, FieldDistance

public interface IDistance

Computes a size of each geometry built

Method Summary

Modifier and Type	Method and Description
double	getBufferDistance(IProjection viewProj, int distanceUnits, int mapUnits) Gets the distance using the specific method
void	setFeature(Feature feature) Sets the current feature
void	setNumberOfRings(int n) Sets the number of rings.

Method Detail

setFeature

void setFeature(Feature feature)

Sets the current feature

Parameters:

feature -

getBufferDistance

double getBufferDistance(IProjection viewProj,
                         int distanceUnits,
                         int mapUnits)

Gets the distance using the specific method

Parameters:

viewProj - Projection

distanceUnits - distance units

mapUnits - map units

Returns:

setNumberOfRings

void setNumberOfRings(int n)

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
