Class InvDatasetFeatureCollection

java.lang.Object

thredds.catalog.InvDataset

thredds.catalog.InvDatasetImpl

thredds.catalog.InvCatalogRef

thredds.catalog.InvDatasetFeatureCollection

All Implemented Interfaces:

CollectionUpdateListener

Direct Known Subclasses:

InvDatasetFcFmrc, InvDatasetFcPoint

@ThreadSafe
public abstract class InvDatasetFeatureCollection
extends InvCatalogRef
implements CollectionUpdateListener

Abstract superclass for Feature Collection InvDatasets. This is a InvCatalogRef subclass. So the reference is placed in the parent, but the catalog itself isnt constructed until the following call from DataRootHandler.makeDynamicCatalog(): match.dataRoot.featCollection.makeCatalog(match.remaining, path, baseURI);

The InvDatasetFeatureCollection object is created once and held in the DataRootHandler's collection of DataRoots.
