Methods
-
buildGeometry(
List< Geometry> geomList) → Geometry -
Build an appropriate
Geometry,MultiGeometry, orGeometryCollectionto contain theGeometrys in it. For example:
-
createEmpty(
int dimension) → Geometry - Creates an empty atomic geometry of the given dimension. If passed a dimension of -1 will create an empty {@link GeometryCollection}.
-
createGeometry(
Geometry? g) → Geometry? - Creates a deep copy of the input {@link Geometry}. The {@link CoordinateSequenceFactory} defined for this factory is used to copy the {@link CoordinateSequence}s of the input geometry.
-
createGeometryCollection(
List< Geometry> ? geometries) → GeometryCollection - Creates a GeometryCollection using the given Geometries; a null or empty array will create an empty GeometryCollection.
-
createGeometryCollectionEmpty(
) → GeometryCollection - Constructs an empty {@link GeometryCollection} geometry.
-
createLinearRing(
List< Coordinate> ? coordinates) → LinearRing - Creates a {@link LinearRing} using the given {@link Coordinate}s. A null or empty array creates an empty LinearRing. The points must form a closed and simple linestring. @param coordinates an array without null elements, or an empty array, or null @return the created LinearRing @throws IllegalArgumentException if the ring is not closed, or has too few points
-
createLinearRingEmpty(
) → LinearRing - Constructs an empty {@link LinearRing} geometry.
-
createLinearRingSeq(
CoordinateSequence? coordinates) → LinearRing - Creates a {@link LinearRing} using the given {@link CoordinateSequence}. A null or empty array creates an empty LinearRing. The points must form a closed and simple linestring.
-
createLineString(
List< Coordinate> ? coordinates) → LineString - Creates a LineString using the given Coordinates. A null or empty array creates an empty LineString.
-
createLineStringEmpty(
) → LineString - Constructs an empty {@link LineString} geometry.
-
createLineStringSeq(
CoordinateSequence? coordinates) → LineString - Creates a LineString using the given CoordinateSequence. A null or empty CoordinateSequence creates an empty LineString.
-
createMultiLineString(
List< LineString> ? lineStrings) → MultiLineString - Creates a MultiLineString using the given LineStrings; a null or empty array will create an empty MultiLineString.
-
createMultiLineStringEmpty(
) → MultiLineString - Constructs an empty {@link MultiLineString} geometry.
-
createMultiPoint(
List< Point> ? point) → MultiPoint - Creates a {@link MultiPoint} using the given {@link Point}s. A null or empty array will create an empty MultiPoint.
-
createMultiPointEmpty(
) → MultiPoint - Constructs an empty {@link MultiPoint} geometry.
-
createMultiPointFromCoords(
List< Coordinate> ? coordinates) → MultiPoint - Creates a {@link MultiPoint} using the given {@link Coordinate}s. A null or empty array will create an empty MultiPoint.
-
createMultiPointSeq(
CoordinateSequence? coordinates) → MultiPoint -
Creates a {@link MultiPoint} using the
points in the given {@link CoordinateSequence}.
A
nullor empty CoordinateSequence creates an empty MultiPoint. -
createMultiPolygon(
List< Polygon> ? polygons) → MultiPolygon - Creates a MultiPolygon using the given Polygons; a null or empty array will create an empty Polygon. The polygons must conform to the assertions specified in the OpenGIS Simple Features Specification for SQL.
-
createMultiPolygonEmpty(
) → MultiPolygon - Constructs an empty {@link MultiPolygon} geometry.
-
createPoint(
Coordinate? coordinate) → Point - Creates a Point using the given Coordinate. A null Coordinate creates an empty Geometry.
-
createPointEmpty(
) → Point - Constructs an empty {@link Point} geometry.
-
createPointSeq(
CoordinateSequence? coordinates) → Point - Creates a Point using the given CoordinateSequence; a null or empty CoordinateSequence will create an empty Point.
-
createPolygon(
LinearRing? shell, List< LinearRing> ? holes) → Polygon -
Constructs a
Polygonwith the given exterior boundary and interior boundaries. -
createPolygonEmpty(
) → Polygon - Constructs an empty {@link Polygon} geometry.
-
createPolygonFromCoords(
List< Coordinate> ? shell) → Polygon -
Constructs a
Polygonwith the given exterior boundary. -
createPolygonFromRing(
LinearRing? shell) → Polygon -
Constructs a
Polygonwith the given exterior boundary. -
createPolygonSeq(
CoordinateSequence shell) → Polygon -
Constructs a
Polygonwith the given exterior boundary. -
getCoordinateSequenceFactory(
) → CoordinateSequenceFactory -
getPrecisionModel(
) → PrecisionModel - Returns the PrecisionModel that Geometries created by this factory will be associated with.
-
getSRID(
) → int - Gets the SRID value defined for this factory.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toGeometry(
Envelope envelope) → Geometry - Creates a {@link Geometry} with the same extent as the given envelope. The Geometry returned is guaranteed to be valid. To provide this behaviour, the following cases occur:
-
toString(
) → String -
A string representation of this object.
