| GeometryFactory | | public class GeometryFactory implements Serializable(Code) | | Supplies a set of utility methods for building Geometry objects from lists
of Coordinates.
Note that the factory constructor methods do not change the input coordinates in any way.
In particular, they are not rounded to the supplied PrecisionModel.
It is assumed that input Coordinates meet the given precision.

| GeometryFactory | | public GeometryFactory(PrecisionModel precisionModel, int SRID)(Code) | | Constructs a GeometryFactory that generates Geometries having the given
PrecisionModel and spatial-reference ID, and the default CoordinateSequence
implementation.

| GeometryFactory | | public GeometryFactory()(Code) | | Constructs a GeometryFactory that generates Geometries having a floating
PrecisionModel and a spatial-reference ID of 0.
|
| buildGeometry | | public Geometry buildGeometry(Collection geomList)(Code) | | Build an appropriate Geometry, MultiGeometry, or
GeometryCollection to contain the Geometrys in
it.
For example:
- If
geomList contains a single Polygon,
the Polygon is returned.
- If
geomList contains several Polygons, a
MultiPolygon is returned.
- If
geomList contains some Polygons and
some LineStrings, a GeometryCollection is
returned.
- If
geomList is empty, an empty GeometryCollection
is returned
Note that this method does not "flatten" Geometries in the input, and hence if
any MultiGeometries are contained in the input a GeometryCollection containing
them will be returned.
Parameters:
geomList - the Geometrys to combine a Geometry of the "smallest", "mosttype-specific" class that can contain the elements of geomList. |
