Constructor Detail

MultiPoint

public MultiPoint(Point[] points,
                  PrecisionModel precisionModel,
                  int SRID)
Deprecated. Use GeometryFactory instead

Constructs a MultiPoint.

Parameters:
points - the Points for this MultiPoint , or null or an empty array to create the empty geometry. Elements may be empty Points, but not nulls.
precisionModel - the specification of the grid of allowable points for this MultiPoint
SRID - the ID of the Spatial Reference System used by this MultiPoint

MultiPoint

public MultiPoint(Point[] points,
                  GeometryFactory factory)
Parameters:
points - the Points for this MultiPoint , or null or an empty array to create the empty geometry. Elements may be empty Points, but not nulls.
Method Detail

getDimension

public int getDimension()
Description copied from class: Geometry
Returns the dimension of this geometry. The dimension of a geometry is is the topological dimension of its embedding in the 2-D Euclidean plane. In the JTS spatial model, dimension values are in the set {0,1,2}.

Note that this is a different concept to the dimension of the vertex Coordinates. The geometry dimension can never be greater than the coordinate dimension. For example, a 0-dimensional geometry (e.g. a Point) may have a coordinate dimension of 3 (X,Y,Z).

Overrides:
getDimension in class GeometryCollection
Returns:
the topological dimension of this geometry.

getBoundaryDimension

public int getBoundaryDimension()
Description copied from class: Geometry
Returns the dimension of this Geometrys inherent boundary.

Overrides:
getBoundaryDimension in class GeometryCollection
Returns:
the dimension of the boundary of the class implementing this interface, whether or not this object is the empty geometry. Returns Dimension.FALSE if the boundary is the empty geometry.

getGeometryType

public java.lang.String getGeometryType()
Description copied from class: Geometry
Returns the name of this object's com.vivid.jts.geom interface.

Overrides:
getGeometryType in class GeometryCollection
Returns:
the name of this Geometrys most specific com.vividsolutions.jts.geom interface

getBoundary

public Geometry getBoundary()
Gets the boundary of this geometry. Zero-dimensional geometries have no boundary by definition, so an empty GeometryCollection is returned.

Overrides:
getBoundary in class GeometryCollection
Returns:
an empty GeometryCollection
See Also:
Geometry.getBoundary()

isValid

public boolean isValid()
Description copied from class: Geometry
Tests the validity of this Geometry. Subclasses provide their own definition of "valid".

Overrides:
isValid in class Geometry
Returns:
true if this Geometry is valid
See Also:
IsValidOp

equalsExact

public boolean equalsExact(Geometry other,
                           double tolerance)
Description copied from class: Geometry
Returns true if the two Geometrys are exactly equal, up to a specified distance tolerance. Two Geometries are exactly equal within a distance tolerance if and only if: This method does not test the values of the GeometryFactory, the SRID, or the userData fields.

To properly test equality between different geometries, it is usually necessary to Geometry.normalize() them first.

Overrides:
equalsExact in class GeometryCollection
Parameters:
other - the Geometry with which to compare this Geometry
tolerance - distance at or below which two Coordinates are considered equal
Returns:
true if this and the other Geometry have identical structure and point values, up to the distance tolerance.
See Also:
Geometry.equalsExact(Geometry), Geometry.normalize(), Geometry.norm()

getCoordinate

protected Coordinate getCoordinate(int n)
Returns the Coordinate at the given position.

Parameters:
n - the index of the Coordinate to retrieve, beginning at 0
Returns:
the nth Coordinate
