                double y)

Adds a Point to this MultiPoint with given x, y coordinates.

add

public void add(double x,
                double y,
                double z)

Adds a Point to this MultiPoint with given x, y, z coordinates.

add

public void add(MultiVertexGeometryImpl src,
                int beginIndex,
                int endIndex)

Appends points from another MultiVertexGeometryImpl at the end of this one.

Parameters:

src - The source MultiVertexGeometryImpl

addPoints

public void addPoints(Point2D[] points)

insertPoint

public void insertPoint(int beforePointIndex,
                        Point pt)

removePoint

void removePoint(int pointIndex)

resize

public void resize(int pointCount)

Resizes the MultiPoint to have the given size.

_copyToImpl

void _copyToImpl(MultiVertexGeometryImpl mvg)

Description copied from class: MultiVertexGeometryImpl

\internal CHildren implement this method to copy additional information

Specified by:

_copyToImpl in class MultiVertexGeometryImpl

setEmpty

public void setEmpty()

Description copied from class: Geometry

Returns the geometry to its original initialization state by releasing all data referenced by the geometry.

Specified by:

setEmpty in class Geometry

applyTransformation

public void applyTransformation(Transformation2D transform)

Description copied from class: Geometry

Applies 2D affine transformation in XY plane.

Specified by:

applyTransformation in class Geometry

Parameters:

transform - The affine transformation to be applied to this geometry.

applyTransformation

void applyTransformation(Transformation3D transform)

Description copied from class: Geometry

Applies 3D affine transformation. Adds Z attribute if it is missing.

Specified by:

applyTransformation in class Geometry

Parameters:
