Interface MultiPolygon

All Superinterfaces:

Cloneable, Comparable<Object>, DataTypeProxy, Geometry, GeometryCollection, Polygonal, Serializable

All Known Implementing Classes:

AbstractMultiPolygon, MultiPolygonImpl, PreparedMultiPolygon

public interface MultiPolygon
extends GeometryCollection, Polygonal

Models a collection of Polygons.

As per the OGC SFS specification, the Polygons in a MultiPolygon may not overlap, and may only touch at single points. This allows the topological point-set semantics to be well-defined.

normalize

MultiPolygon normalize()

Description copied from interface: Geometry

Converts this Geometry to normal form (or canonical form ). Normal form is a unique representation for Geometry s. It can be used to test whether two Geometrys are equal in a way that is independent of the ordering of the coordinates within them. Normal form equality is a stronger condition than topological equality, but weaker than pointwise equality. The definitions for normal form use the standard lexicographical ordering for coordinates. "Sorted in order of coordinates" means the obvious extension of this ordering to sequences of coordinates.

Specified by:

normalize in interface Geometry

Specified by:

normalize in interface GeometryCollection

Returns:

a normalized copy of this geometry.

Geometry.normalize()

reverse

MultiPolygon reverse()

Creates a MultiPolygon with every component reversed. The order of the components in the collection are not reversed.

Specified by:

reverse in interface Geometry

Returns:

a MultiPolygon in the reverse order
