Field Summary

boolean	isM
boolean	isZ
double	m The m value.
double	x The x value.
double	y The y value.
double	z The z value.

Constructor Summary

ShapePoint(boolean z, boolean m)
Constructs one without values, use read to fill it.

ShapePoint(byte[] bytes, int offset)
Just reads x and y from the byte array.

ShapePoint(Point p)
Creates a new PointZ from deegree Point.

ShapePoint(Position p)
Creates a new PointZ from deegree Position.

Method Summary

com.vividsolutions.jts.geom.Coordinate	export()
void	extend(double mVal) Extends this point with m values, so it is a PointM
void	extend(double zVal, double mVal) Extends this point with z and m values, so it is a PointZ
int	getByteLength()
ShapeEnvelope	getEnvelope()
Geometry	getGeometry() This creates a Point object.
int	getType()
int	read(byte[] bytes, int offset) Reads the object from a byte array.
String	toString()

Constructor Detail

ShapePoint

public ShapePoint(boolean z,
                  boolean m)

Constructs one without values, use read to fill it.

Parameters:

z - if PointZ

m - if PointM

ShapePoint

public ShapePoint(Point p)

Creates a new PointZ from deegree Point.

Parameters:

p -

ShapePoint

public ShapePoint(Position p)

Creates a new PointZ from deegree Position.

Parameters:

p -

ShapePoint

public ShapePoint(byte[] bytes,
                  int offset)

Just reads x and y from the byte array.

Parameters:

bytes -

offset -

Method Detail

export

public com.vividsolutions.jts.geom.Coordinate export()

Returns:

the Point as (x, y, NaN), the PointZ as (x, y, z) Coordinate

extend

public void extend(double zVal,
                   double mVal)

Extends this point with z and m values, so it is a PointZ

Parameters:

zVal -

mVal -

extend

public void extend(double mVal)

Extends this point with m values, so it is a PointM

Parameters:

mVal -

getByteLength

public int getByteLength()

Specified by:

getByteLength in interface Shape

Returns:

the number of bytes necessary to write this instance.

read

public int read(byte[] bytes,
                int offset)

Description copied from interface: Shape

Reads the object from a byte array.

Specified by:

read in interface Shape

offset - where to start reading

Returns:

the new offset or -1, if the type was wrong.

write

public int write(byte[] bytes,
                 int offset)

Description copied from interface: Shape

Writes the object to a byte array.

Specified by:

write in interface Shape

Returns:

the new offset.

getType

public int getType()

Specified by:

getType in interface Shape

Returns:

the type of the shape

getEnvelope

public ShapeEnvelope getEnvelope()

Specified by:

getEnvelope in interface Shape

Returns:

null, points do not have an envelope

See Also:

Shape.getEnvelope()

getGeometry

public Geometry getGeometry()
                     throws ShapeGeometryException

This creates a Point object.

Specified by:

getGeometry in interface Shape

Returns:

the shape as deegree Geometry

Throws:

ShapeGeometryException - if the deegree geometry could not be constructed

See Also:

Shape.getGeometry()

toString

public String toString()

Overrides:

toString in class Object
