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(boolean z, boolean m, CoordinateSystem crs)
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.

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(boolean z,
                  boolean m,
                  CoordinateSystem crs)

Constructs one without values, use read to fill it.

Parameters:

crs - CoordinateSystem of the shape

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
