Methods

copy(CoordinateSequence seq) → CoordinateSequence
Convenience method which provides a standard way of copying {@link CoordinateSequence}s @param seq the sequence to copy @return a deep copy of the sequence
inherited
createCoordinateSequence(List<Coordinate> coords) → CoordinateSequence
Convenience method which provides standard way of creating a {@link CoordinateSequence}
inherited
createValidArea(Geometry rawAreaGeom) → Geometry
Creates a valid area geometry from one that possibly has bad topology (i.e. self-intersections). Since buffer can handle invalid topology, but always returns valid geometry, constructing a 0-width buffer "corrects" the topology. Note this only works for area geometries, since buffer always returns areas. This also may return empty geometries, if the input has no actual area. If the input is empty or is not polygonal, this ensures that POLYGON EMPTY is returned.
getInputGeometry() → Geometry
Utility function to make input geometry available
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited
transform(Geometry inputGeom) → Geometry
inherited
transformCoordinates(CoordinateSequence coords, Geometry parent) → CoordinateSequence
Transforms a {@link CoordinateSequence}. This method should always return a valid coordinate list for the desired result type. (E.g. a coordinate list for a LineString must have 0 or at least 2 points). If this is not possible, return an empty sequence - this will be pruned out.
override
transformGeometryCollection(GeometryCollection geom, Geometry parent) → Geometry
inherited
transformLinearRing(LinearRing geom, Geometry parent) → Geometry
Simplifies a LinearRing. If the simplification results in a degenerate ring, remove the component.
override
transformLineString(LineString geom, Geometry parent) → Geometry
Transforms a {@link LineString} geometry.
inherited
transformMultiLineString(MultiLineString geom, Geometry parent) → Geometry
inherited
transformMultiPoint(MultiPoint geom, Geometry parent) → Geometry
inherited
transformMultiPolygon(MultiPolygon geom, Geometry parent) → Geometry
Simplifies a MultiPolygon, fixing it if required.
override
transformPoint(Point geom, Geometry parent) → Geometry
inherited
transformPolygon(Polygon geom, Geometry parent) → Geometry
Simplifies a polygon, fixing it if required.

Operators

operator ==(Object other) → bool
The equality operator.
