                      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.

Throws:

XMLStreamException

XMLParsingException

IllegalArgumentException

OutsideCRSDomainException

UnknownCRSException

TransformationException
