Interface Position

All Known Implementing Classes:

PositionImpl

public interface Position

A sequence of decimals numbers which when written on a width are a sequence of coordinate positions. The width is derived from the CRS or coordinate dimension of the container.

Method Summary

double	getAccuracy() returns the accuracy the position is defined.
double[]	getAsArray() NOTE: The returned array always has a length of 3, regardless of the dimension.
javax.vecmath.Point3d	getAsPoint3d()
int	getCoordinateDimension()
double	getX()
double	getY()
double	getZ()
void	setAccuracy(double accuracy)
void	translate(double[] d) translates the coordinates of the position.

Method Detail

getX

double getX()

Returns:

the x-value of the point

getY

double getY()

Returns:

the y-value of the point

getZ

double getZ()

Returns:

the z-value of the point

getCoordinateDimension

int getCoordinateDimension()

Returns:

the coordinate dimension of the position

getAsArray

double[] getAsArray()

NOTE: The returned array always has a length of 3, regardless of the dimension. This is due to a limitation in the coordinate transformation package (proj4), which expects coordinates to have 3 dimensions.

Returns:

the x- and y-value of the point as a two dimensional array the first field contains the x- the second field the y-value.

translate

void translate(double[] d)

translates the coordinates of the position.

Parameters:

d - the first coordinate of the position will be translated by the first field of d the second coordinate by the second field of d and so on...

getAccuracy

double getAccuracy()

returns the accuracy the position is defined. The accuracy is measured in values of the CRS the positions coordinates are stored

Returns:

the accuracy the position is defined

setAccuracy

void setAccuracy(double accuracy)

Parameters:

accuracy -

getAsPoint3d

javax.vecmath.Point3d getAsPoint3d()

Returns:

the position as a point3d
