public abstract class AbstractGeometryCollection<P extends Position,G extends Geometry<P>>
extends Geometry<P>
implements Complex<P,G>

A Geometry that is an ordered collection of some number of Geometrys.

All elements in a GeometryCollection must be in the same CoordinateReferenceSystem, which is also the CoordinateReferenceSystem for the GeometryCollection.

Constructor Detail

AbstractGeometryCollection

@SafeVarargs
public AbstractGeometryCollection(G... geometries)

Constructs a GeometryCollection from the specified Geometrys.

Parameters:

geometries - the Geometrys that are the elements of the constructed GeometryCollection.

AbstractGeometryCollection

public AbstractGeometryCollection(CoordinateReferenceSystem<P> crs)

Constructs an empty GeometryCollection

Method Detail

getNumGeometries

public int getNumGeometries()

Returns the number of elements in this GeometryCollection.

Specified by:

getNumGeometries in interface Complex<P extends Position,G extends Geometry<P>>

Returns:

the number of elements of this instance.

getComponentType

public Class<? extends Geometry> getComponentType()

Description copied from interface: Complex

Returns the Class of which all constituent Geometrys are instances.

Specified by:

getComponentType in interface Complex<P extends Position,G extends Geometry<P>>

Returns:

the Class of which all constituent Geometrys are instances.

components

public G[] components()

Returns the components

Specified by:

components in interface Complex<P extends Position,G extends Geometry<P>>

Returns:

an array containing all component objects

getGeometryN

public G getGeometryN(int num)

Returns the Geometry element at the specified (zero-based) position in this GeometryCollection.

Parameters:

num - the position in the collection of the requested Geometry

Returns:

the element Geometry at the position specified by the num parameter.

getDimension

public int getDimension()

Description copied from class: Geometry

the GeometryType of this instance.

iterator

public Iterator<G> iterator()

Creates an Iterator over the elements of this GeometryCollection.

Specified by:

iterator in interface Iterable<P extends Position>

Returns:

an Iterator over the elements of this GeometryCollection.

accept

public void accept(GeometryVisitor<P> visitor)

Accepts the GeometryVisitor, and will pass it to it's constituent Geometries.

Specified by:

accept in class Geometry<P extends Position>

Parameters:

visitor -
