Constructor Detail

IlvGeocentricTransform

protected IlvGeocentricTransform(IlvCoordinateSystem sourceCS,
                                 IlvCoordinateSystem targetCS)

Constructor.

IlvGeocentricTransform

protected IlvGeocentricTransform(IlvInputStream stream)
                          throws IlvReadFileException

Reads an IlvGeocentricTransformation from the specified input stream.

Parameters:

stream - The IlvInputStream.

Throws:

IlvReadFileException - If a transformation cannot be read from the input stream.

Method Detail

write

public void write(IlvOutputStream stream)
           throws IOException

Writes this transformation to the specified output file.

Specified by:

write in interface IlvPersistentObject

Parameters:

stream - The IlvOutputStream.

Throws:

IOException - If an error occurs.

transform

public IlvCoordinate[] transform(IlvCoordinate[] sourceCP,
