Method Detail

appendVertex

public <V extends Geometry> V appendVertex(Point newPoint,
                                  int... geometryId)

Specified by:

appendVertex in interface Geometry

Overrides:

appendVertex in class AbstractGeometryCollection

copy

public <V extends Geometry> V copy(GeometryFactory geometryFactory)

Description copied from interface: Geometry

Create a copy of the geometry io the requried geometry factory. Projecting to the required coordinate system and applying the precision model.

Specified by:

copy in interface Geometry

Overrides:

copy in class AbstractGeometryCollection

Parameters:

geometryFactory - The geometry factory to convert the geometry to.

Returns:

The converted geometry

equalsExact

public boolean equalsExact(Geometry other,
                  double tolerance)

Description copied from class: AbstractGeometry

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:

• they have the same structure
• they have the same values for their vertices, within the given tolerance distance, in exactly the same order.

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 AbstractGeometry.normalize() them first.

Specified by:

equalsExact in interface Geometry

Overrides:

equalsExact in class AbstractGeometryCollection

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.

AbstractGeometry.equals(2,Geometry), AbstractGeometry.normalize(), #norm()

getBoundary

public Geometry getBoundary()

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

Specified by:

getBoundary in interface Geometry

Overrides:

getBoundary in class AbstractGeometryCollection

Returns:

an empty GeometryCollection

See Also:

Geometry.getBoundary()

getBoundaryDimension

public int getBoundaryDimension()

Description copied from class: AbstractGeometry

Returns the dimension of this Geometrys inherent boundary.

Specified by:

getBoundaryDimension in interface Geometry

Overrides:

getBoundaryDimension in class AbstractGeometryCollection

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.

getCoordinate

protected Point getCoordinate(int n)

Returns the Coordinate at the given position.

Parameters:

n - the partIndex of the Coordinate to retrieve, beginning at 0

Returns:

the nth Coordinate

getCoordinate

public double getCoordinate(int partIndex,
                   int axisIndex)

Specified by:

getCoordinate in interface MultiPoint

getDataType

public DataType getDataType()

Specified by:

getDataType in interface DataTypeProxy

Overrides:

getDataType in class AbstractGeometryCollection

getDimension

public int getDimension()

Description copied from class: AbstractGeometry

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 Coordinatess. 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).

Specified by:

getDimension in interface Geometry

Overrides:

getDimension in class AbstractGeometryCollection

Returns:

the topological dimension of this geometry.

getPoint

public Point getPoint(int partIndex)

Specified by:

getPoint in interface MultiPoint

getPoints

public <V extends Point> List<V> getPoints()

Specified by:

getPoints in interface MultiPoint

getSegment

public Segment getSegment(int... segmentId)

Description copied from interface: Geometry

Get the Segment at the specified vertexId (see Segment.getSegmentId()).

Specified by:

getSegment in interface Geometry

Overrides:

getSegment in class AbstractGeometryCollection

Returns:

The vertex or null if it does not exist.

getToVertex

public Vertex getToVertex(int... vertexId)

Description copied from interface: Geometry

Get the Vertex at the specified vertexId starting at the end of the geometry (see Vertex.getVertexId()).

Specified by:

getToVertex in interface Geometry

Overrides:

getToVertex in class AbstractGeometryCollection

Parameters:

vertexId - The id of the vertex.

Returns:

The vertex or null if it does not exist.

getVertex

public Vertex getVertex(int... vertexId)

Description copied from interface: Geometry

Get the Vertex at the specified vertexId (see Vertex.getVertexId()).

Specified by:

getVertex in interface Geometry

Overrides:

getVertex in class AbstractGeometryCollection

Parameters:

vertexId - The id of the vertex.

Returns:

The vertex or null if it does not exist.

isEquivalentClass

protected boolean isEquivalentClass(Geometry other)

Description copied from class: AbstractGeometry

Returns whether the two Geometrys are equal, from the point of view of the equalsExact method. Called by equalsExact . In general, two Geometry classes are considered to be "equivalent" only if they are the same class. An exception is LineString , which is considered to be equivalent to its subclasses.

Overrides:

isEquivalentClass in class AbstractGeometryCollection

Parameters:

other - the Geometry with which to compare this Geometry for equality

Returns:

true if the classes of the two Geometry s are considered to be equal by the equalsExact method.

isValid

public boolean isValid()

Description copied from class: AbstractGeometry

Tests whether this Geometry is topologically valid, according to the OGC SFS specification.

For validity rules see the Javadoc for the specific Geometry subclass.

Specified by:

isValid in interface Geometry

Overrides:

isValid in class AbstractGeometry

Returns:

true if this Geometry is valid

See Also:

IsValidOp

moveVertex

public <V extends Geometry> V moveVertex(Point newPoint,
                                int... vertexId)

Specified by:

moveVertex in interface Geometry

Overrides:

moveVertex in class AbstractGeometryCollection

normalize

public MultiPoint normalize()

Description copied from class: AbstractGeometry

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

Specified by:

normalize in interface MultiPoint

Overrides:

normalize in class AbstractGeometryCollection

Returns:

a normalized copy of this geometry.

See Also:

AbstractGeometry.normalize()

segments

public IteratorReader<Segment> segments()

Specified by:

segments in interface Geometry

Overrides:

segments in class AbstractGeometryCollection

toClockwise

public <G extends Geometry> G toClockwise()

Specified by:

toClockwise in interface Geometry

Overrides:

toClockwise in class AbstractGeometryCollection

toCounterClockwise

public <G extends Geometry> G toCounterClockwise()

Specified by:

toCounterClockwise in interface Geometry

Overrides:

toCounterClockwise in class AbstractGeometryCollection

vertices

public Reader<Vertex> vertices()

Description copied from interface: Geometry

Get an Iterable that iterates over the Vertex of the geometry. For memory efficiency the Vertex returned is the same instance for each call to next on the iterator. If the vertex is required to track the previous vertex then the Vertex.clone() method must be called to get a copy of the vertex.

The Iterable.iterator() method always returns the same Iterator instance. Therefore that method should not be called more than once.

Specified by:

vertices in interface Geometry

Overrides:

vertices in class AbstractGeometryCollection

Returns:

The iterator over the vertices of the geometry.
