Class PositionImpl

java.lang.Object
  org.deegree.model.spatialschema.PositionImpl

All Implemented Interfaces:

Serializable, Position

 class PositionImpl
extends Object
implements Position, Serializable

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.

Constructor Detail

PositionImpl

PositionImpl()

constructor. initializes a point to the coordinate 0/0

PositionImpl

PositionImpl(double x,
             double y)

constructor

Parameters:

x - x-value of the point

y - y-value of the point

PositionImpl

PositionImpl(double x,
             double y,
             double z)

constructor

Parameters:

x - x-value of the point

y - y-value of the point

z - z-value of the point

PositionImpl

PositionImpl(double[] coords)

constructor.

Parameters:

coords - the Coordinates from which the position is build.

Method Detail

getCoordinateDimension

public int getCoordinateDimension()

Specified by:

getCoordinateDimension in interface Position

Returns:

the coordinate dimension of the position

clone

public Object clone()

Overrides:

clone in class Object

Returns:

a shallow copy of the geometry.

getX

public double getX()

Specified by:

getX in interface Position

Returns:

the x-value of this point

getY

public double getY()

Specified by:

getY in interface Position

Returns:

the y-value of this point

getZ

public double getZ()

Specified by:

getZ in interface Position

Returns:

the z-value of this point.

getAsArray

public double[] getAsArray()

Description copied from interface: Position

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.

Specified by:

getAsArray in interface Position

Returns:

the position as a array the first field contains the x- the second field the y-value etc. 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.

translate

public void translate(double[] d)

translate the point by the submitted values. the dz- value will be ignored.

Specified by:

translate in interface Position

Parameters:

d -

equals

public boolean equals(Object other)

compares if all field of other are equal to the corresponding fields of this position

Overrides:

equals in class Object

getAccuracy

public double getAccuracy()

Description copied from interface: Position

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

Specified by:

getAccuracy in interface Position

Returns:

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

setAccuracy

public void setAccuracy(double accuracy)

Specified by:

setAccuracy in interface Position

Parameters:

accuracy -

getAccuracy()

toString

public String toString()

Overrides:

toString in class Object
