public class RegistryStarTable
extends ColumnStarTable

Table representing the flattened results of a registry query. Each row represents an Interface of a Capability of a VOResource, or, in the case that a VOResource has no Capabilities, just a VOResource. Only selected attributes (the most useful?) of these structures are represented here as columns. If you want a more detailed representation of a VOResource object, which is hierarchical, you will need to examine the VOResource objects themselves.
