  org.deegree.gml.geometry.GML3GeometryBaseReader
      org.deegree.gml.geometry.GML3SurfacePatchReader

 class GML3SurfacePatchReader
extends GML3GeometryBaseReader

Handles the parsing of gml:_SurfacePatch elements, i.e concrete element declarations that are in the substitution group of gml:_SurfacePatch.

This class handles all 6 concrete substitutions for gml:_SurfacePatch that are defined in GML 3.1.1:

• Cone
• Cylinder
• PolygonPatch
• Rectangle
• Sphere
• Triangle

Method Detail

parseSurfacePatch

SurfacePatch parseSurfacePatch(XMLStreamReaderWrapper xmlStream,
                               CRS defaultCRS)
                         throws XMLParsingException,
                                XMLStreamException,
                                UnknownCRSException

Returns the object representation for a gml:_SurfacePatch element. Consumes all corresponding events from the associated XMLStream.

• Precondition: cursor must point at the START_ELEMENT event (<gml:_SurfacePatch>)
• Postcondition: cursor points at the corresponding END_ELEMENT event (</gml:_SurfacePatch>)

This method handles all 6 concrete substitutions for gml:_SurfacePatch that are defined in GML 3.1.1:

• Cone
• Cylinder
• PolygonPatch
• Rectangle
• Sphere
• Triangle

Parameters:

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

Returns:

corresponding SurfacePatch object

Throws:

XMLParsingException

XMLStreamException

UnknownCRSException

parsePolygonPatch

PolygonPatch parsePolygonPatch(XMLStreamReaderWrapper xmlStream,
                               CRS defaultCRS)
                         throws XMLParsingException,
                                XMLStreamException,
                                UnknownCRSException

Returns the object representation of a <gml:PolygonPatch> element. Consumes all corresponding events from the associated XMLStream.

• Precondition: cursor must point at the START_ELEMENT event (<gml:PolygonPatch>)
• Postcondition: cursor points at the corresponding END_ELEMENT event (</gml:PolygonPatch>)

Parameters:

defaultCRS - default CRS for the geometry, this is propagated if no deeper srsName attribute is specified

Returns:

corresponding PolygonPatch object

Throws:

XMLParsingException - if a syntactical (or semantic) error is detected in the element

XMLStreamException

UnknownCRSException

parseTriangle

Triangle parseTriangle(XMLStreamReaderWrapper xmlStream,
                       CRS defaultCRS)
                 throws XMLStreamException,
                        XMLParsingException,
                        UnknownCRSException

Returns the object representation of a <gml:Triangle> element. Consumes all corresponding events from the associated XMLStream.

• Precondition: cursor must point at the START_ELEMENT event (<gml:Triangle>)
• Postcondition: cursor points at the corresponding END_ELEMENT event (</gml:Triangle>)

Parameters:

defaultCRS - default srs for the geometry, this is propagated if no deeper srsName attribute is specified

Returns:

corresponding Triangle object

Throws:

XMLParsingException - if a syntactical (or semantic) error is detected in the element

XMLStreamException

UnknownCRSException

XMLParsingException
