Examples of org.locationtech.udig.catalog.ICatalog

org.locationtech.udig.catalog.ICatalog
Interface to capture both the Local Catalog resources and Web Registry Service.
Conceptually provides a searchable Catalog of "Spatial Data Sources". Metadata search is arbitrary.
This class contributes the idea of temporary resources (or scratch layers)
- {@link #createTemporaryResource(Object)
- @link #getTemporaryDescriptorClasses()
Descriptor classes, usually a GeoTools SimpleFeatureType, are used to create a temporary resource that is held in memory. These temporary resources must be saved prior to the application exiting or the contents will be lost.} @author David Zwiers (Refractions Research) @since 0.7.0 @version 1.2 @see IService
