Class ThreddsWmsCatalogue

java.lang.Object

thredds.server.wms.ThreddsWmsCatalogue

All Implemented Interfaces:

uk.ac.rdg.resc.edal.graphics.utils.DatasetCatalogue, uk.ac.rdg.resc.edal.graphics.utils.FeatureCatalogue, uk.ac.rdg.resc.edal.wms.WmsCatalogue

public class ThreddsWmsCatalogue
extends java.lang.Object
implements uk.ac.rdg.resc.edal.wms.WmsCatalogue

Example of an implementation of a WmsCatalogue to work with the TDS. This is a working example, but many of the specifics will need to be implemented differently based on how the THREDDS team decide to configure WMS layers. This WmsCatalogue provides access to a SINGLE dataset. As such, each different dataset requested will have a new instance of this class. NB - No caching is implemented in this WmsCatalogue. I would recommend a cache which is shared amongst all WmsCatalogues, passed in on object construction, and which performs the caching/retrieval in the FeatureCatalogue.getFeaturesForLayer(String, PlottingDomainParams) method. The cache keys will be a pair of the layerName and the PlottingDomainParams, and the cached values will be Collections of DiscreteFeatures.
