uk.ac.rdg.resc.edal.dataset.DatasetFactory

uk.ac.rdg.resc.edal.dataset.cdm.CdmDatasetFactory

thredds.server.wms.TdsWmsDatasetFactory

public class TdsWmsDatasetFactory
extends uk.ac.rdg.resc.edal.dataset.cdm.CdmGridDatasetFactory

Basically, this class exists to use a NetcdfDataset that has been opened by the TDS into ncWMS. We needed to do this to use NcML wrapped datasets being served by the TDS, but since we already get a NetcdfDataset from the TDS side, we might as well pass it along to ncWMS for non-NcML cases too.

Method Detail

setNetcdfDataset

public void setNetcdfDataset(ucar.nc2.dataset.NetcdfDataset ncd)

getNetcdfDatasetFromLocation

protected ucar.nc2.dataset.NetcdfDataset getNetcdfDatasetFromLocation(java.lang.String location,
                                                                      boolean forceRefresh)

None of this matters really. For NcML datasets, we cannot rely on a location, as the ncml is modifying the dataset in memory. So, we are ignoring location and force reset while accssing the NetcdfDataset directly (which is set in ThreddsWmsCatalogue)

Overrides:

getNetcdfDatasetFromLocation in class uk.ac.rdg.resc.edal.dataset.cdm.CdmDatasetFactory

Parameters:

location - - location of the netCDF File

forceRefresh - - this is an ncWMS specific thing

Returns:

Throws:

java.io.IOException
