GeometryBuilder<T extends Geometry, E extends Geometry> class

A builder to create geometry objects of T from GeometryContent.

The type E is used for element types on geometry collections.

This builder supports creating Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon and GeometryCollection objects.

See GeometryContent for more information about these objects.

This builder ignore "empty geometry" types.
