I'm currently using the following mechanism. I extend the class
com.vividsolutions.jump.io.datasource.StandardReaderWriterFileDataSource
as follows:
public static class DeeMapInfoFile extends
StandardReaderWriterFileDataSource {
public DeeMapInfoFile() {
super( new DeegreeMapInfoReader(), null, new String[] { "mid",
"mif" } );
}
}
with the DeegreeMapInfoReader implementing the
com.vividsolutions.jump.io.JUMPReader interface with the method
public FeatureCollection read( DriverProperties dp )
throws Exception;
A solution would be to add an ExtendedJUMPReader with an additional method that
gets called with the layer or something later on. That would enable old plugins
to continue to work, and a simple instanceof tells us with which reader we're
dealing.
Best regards, Andreas
