Method Detail

transform

public void transform(XMLStreamReader reader,
                      XMLStreamWriter writer,
                      org.deegree.cs.coordinatesystems.ICRS sourceCRS,

               throws XMLStreamException,

                      org.deegree.cs.exceptions.TransformationException

Transforms the given input stream, and streams the input into the output directly. If a geometry is found, the geometry is transformed into the target crs. All other events are just copied.

Parameters:

reader - an XMLStream containing some GML Geometries.

writer - the output will be written to this writer, the writer have been opened ( XMLStreamWriter.writeStartDocument(). No XMLStreamWriter.writeEndDocument() will be written as well.

sourceCRS - to be used if the geometries do not define a srsName (or the like) attribute.

gmlVersion - the version of the expected geometries.

testValidArea - true if the incoming geometries should be checked against the valid domain of the crs they are defined in.

requestedTransformation - can be null

Throws:

XMLStreamException

org.deegree.commons.xml.XMLParsingException

IllegalArgumentException

org.deegree.cs.exceptions.OutsideCRSDomainException

org.deegree.cs.exceptions.UnknownCRSException

org.deegree.cs.exceptions.TransformationException
