Constructor Summary

protected	MultiGeometryImpl(CoordinateSystem crs) Creates an empty MultiGeometryImpl instance with a given CoordinateSystem.
protected	MultiGeometryImpl(Geometry[] members, CoordinateSystem crs) Creates a MultiGeometryImpl with a given CoordinateSystem that contains the provided Geometry objects.

Method Summary

protected void	calculateParam() Calculates the value of the following member variables: dimension GeometryImpl.envelope GeometryImpl.centroid
int	getCoordinateDimension() The operation "coordinateDimension" shall return the dimension of the coordinates that define this Geometry, which must be the same as the coordinate dimension of the coordinate reference system for this Geometry.
int	getDimension() Returns the dimension of the aggregation, i.e. the maximum dimension of all member geometries.

Constructor Detail

MultiGeometryImpl

protected MultiGeometryImpl(CoordinateSystem crs)

Creates an empty MultiGeometryImpl instance with a given CoordinateSystem.

Parameters:

crs - coordinate system

MultiGeometryImpl

protected MultiGeometryImpl(Geometry[] members,
                            CoordinateSystem crs)

Creates a MultiGeometryImpl with a given CoordinateSystem that contains the provided Geometry objects.

Parameters:

members - geometries contained in the MultiGeometry

crs - coordinate system

Method Detail

getCoordinateDimension

public int getCoordinateDimension()

The operation "coordinateDimension" shall return the dimension of the coordinates that define this Geometry, which must be the same as the coordinate dimension of the coordinate reference system for this Geometry.

Specified by:

getCoordinateDimension in interface Geometry

Returns:

the actual dimension

getDimension

public int getDimension()

Returns the dimension of the aggregation, i.e. the maximum dimension of all member geometries.

Specified by:

getDimension in interface Geometry

Returns:

the maximum dimension of all member geometries

calculateParam

protected void calculateParam()

Calculates the value of the following member variables:

• dimension
• GeometryImpl.envelope
• GeometryImpl.centroid

Specified by:

calculateParam in class GeometryImpl
