Package ucar.nc2.ft2.coverage

Class CoverageDatasetFactory

java.lang.Object

ucar.nc2.ft2.coverage.CoverageDatasetFactory

public class CoverageDatasetFactory
extends Object

factory for CoverageDataset 1) Remote CdmrFeatureDataset: cdmremote:url 2) GRIB collections: must be a grib file, or grib index file 3) DtCoverageDataset (forked from ucar.nc2.dt.grid), the cdm IOSP / CoordSys stack

Would like to add a separate implementation for FMRC collections

Parameters:

endpoint - cdmrFeature:url, local GRIB data or index file, or NetcdfDataset location

        ucar.nc2.util.Optional opt = CoverageDatasetFactory.openCoverageDataset(location);
        if (!opt.isPresent()) {
          JOptionPane.showMessageDialog(null, opt.getErrorMessage());
          return false;
        }
        covDatasetCollection = opt.get();
