Class Ri1RegistryTableLoadDialog

java.lang.Object

uk.ac.starlink.table.gui.AbstractTableLoadDialog

uk.ac.starlink.vo.Ri1RegistryTableLoadDialog

All Implemented Interfaces:

TableLoadDialog

public class Ri1RegistryTableLoadDialog
extends AbstractTableLoadDialog

Table load dialogue implementation for performing a simple query on a registry. The user can choose which registry to use, and the text of the query (WHERE clause) to make, and a StarTable is returned which contains all the detail of the resources found.

This is not very user-friendly or useful, and hence is somewhat deprecated. A TAP query on a Relational Registry service (RegTAP) is usually a better way to acquire registry information.
