datumShift -

Method Detail

getConversionInfoForID

protected Helmert getConversionInfoForID(String infoID)
                                  throws CRSConfigurationException

Parameters:

infoID - to get the conversioninfo from.

Returns:

the configured wgs84 conversion info parameters.

Throws:

CRSConfigurationException

getTransformationForId

public Transformation getTransformationForId(String transformId)
                                      throws CRSConfigurationException

Parameters:

transformId - to get the transformation for.

Returns:

the configured wgs84 conversion info parameters.

Throws:

CRSConfigurationException

parseTransformation

protected Transformation parseTransformation(XMLStreamReader reader)
                                      throws XMLStreamException

Parameters:

reader - to

Returns:

the next datum on the stream.

Throws:

XMLStreamException

expectedRootName

protected QName expectedRootName()

Specified by:

expectedRootName in class DefinitionParser

Returns:

the top level element of a configuration file.

getTransformation

public Transformation getTransformation(ICRS sourceCRS,
                                        ICRS targetCRS)

Parameters:

sourceCRS -

targetCRS -

Returns:

the (concatenated) configured transform between the source and the target crs. Calling this method is not the same as creating a new Transformation chain with the TransformationFactory#createFromCoordinateSystems(CRS, ICRS)

getConversionInfo

public Helmert getConversionInfo(GeographicCRS sourceCRS)

Parameters:

sourceCRS -

Returns:

the configured helmert for the given source crs or null
