Examples of WKTParser

ca.carleton.gcrc.geom.wkt.WktParser
org.geotools.geometry.text.WKTParser
This class is used to parse well known text (WKT) which describes an ISO 19107 Geometry. The grammar described comes from the ISO 19125-1 spec which describes feature geometry. It doesn't seem to exactly mesh up with the geometry as described in 19107 so not all of the grammar is supported.
The types in the WKT format, and their mappings:
- POINT org.opengis.geometry.primitive.Point
- LINESTRING org.opengis.geometry.primitive.Curve
- POLYGON org.opengis.geometry.primitive.Surface
- MULTIPOINT org.opengis.geometry.coordinate.aggregate.MultiPoint Note that there is no factory method for MultiPoint.
  For now, to keep implementation-independance I'm returning it as a List
- MULTILINESTRING no matching type in the GeoAPI interfaces Could also be returned as list.
  Not handled for now
- MULTIPOLYGON no matching type in the GeoAPI interfaces Could also be returned as list.
  Not handled for now
> Please note that this parser is not thread safe; you can however reuse the parser. @author Jody Garnett @author Joel Skelton @since 2.5 @source $URL$ @version $Id$
