Examples of ThreddsDataFactory

ucar.nc2.thredds.ThreddsDataFactory
This tries to translate a THREDDS InvDataset into a data object that can be used, either as a NetcdfDataset or as a FeatureDataset.
As input, it can take
1. An InvAccess object.
2. An InvDataset object. If the InvDataset has more that one InvAccess, it has to try to choose which to use, based on what Service type we know how to work with.
3. A url of the form [thredds:]catalog.xml#datasetId. In this case it opens the catalog, and looks for the InvDataset with the given datasetId.
4. A url of the form thredds:resolve:resolveURL. In this case it expects that the URL will return a catalog with a single top level dataset, which is the "resolved" dataset.
It annotates the NetcdfDataset with info from the InvDataset.
You can reuse a ThreddsDataFactory, but only within a single thread. @author caron
