All Implemented Interfaces:

GMLGeometryReader

public class GML3GeometryReader
extends Object
implements GMLGeometryReader

Parser for geometry and geometry-related constructs from the GML 3 specification series (3.0/3.1/3.2).

Supports the following geometry elements:

• Point
• LineString
• Curve
• OrientableCurve
• CompositeCurve
• LinearRing
• Ring
• Polygon
• Surface
• CompositeSurface
• OrientableSurface
• PolyhedralSurface
• Surface
• Tin
• TriangulatedSurface
• Solid

• MultiLineString
• MultiCurve
• MultiPolygon
• MultiSurface
• MultiGeometry

Additionally, parsing of Envelope elements is supported, parseEnvelope(XMLStreamReaderWrapper) and parseGeometryOrEnvelope(XMLStreamReaderWrapper).

TODO Currently unsupported are the elements from the _ImplicitGeometry substitution group, i.e. Grid and RectifiedGrid).

Returns the object representation of a (<gml:TriangulatedSurface>) element. Consumes all corresponding events from the given XMLStream.

Parameters:

xmlStream - cursor must point at the START_ELEMENT event (<gml:TriangulatedSurface>), points at the corresponding END_ELEMENT event (</gml:TriangulatedSurface>) afterwards

defaultCRS - default CRS for the geometry, this is only used if the "gml:TriangulatedSurface" has no srsName attribute

Returns:

                                                   org.deegree.cs.exceptions.UnknownCRSException

Returns the object representation of a (<gml:Tin>) element. Consumes all corresponding events from the given XMLStream.

Note: GML 3.1.1 specifies both "gml:trianglePatches" and "gml:controlPoint" properties for "gml:Tin". This is apparently redundant, and consequently (?) GML 3.2.1 only allows the controlPoint property here. This method copes with this by only using the controlPoints for building the Tin object.

Parameters:

xmlStream - cursor must point at the START_ELEMENT event (<gml:Tin>), points at the corresponding END_ELEMENT event (</gml:Tin>) afterwards

defaultCRS - default CRS for the geometry, this is only used if the "gml:Tin" has no srsName attribute

Returns:

corresponding Tin object
