Retrieving the External Links for an Object

Use the RegistryObject.getExternalLinks method to retrieve a Collection of the object’s external links. For each external link, you can retrieve its name, description, and value. For an external link, the name is optional. The following code fragment retrieves and displays an object’s external links.

Collection exLinks = obj.getExternalLinks();
Iterator exLinkIter = exLinks.iterator();
while (exLinkIter.hasNext()) {
    ExternalLink exLink = (ExternalLink) exLinkIter.next();
    String name = exLink.getName().getValue();
    if (name != null) {
        System.out.println("  External link name is " + name);
    }
    String description = exLink.getDescription().getValue();
    System.out.println("  External link description is " +
        description);
    String externalURI = exLink.getExternalURI();
    System.out.println("  External link URI is " +
         externalURI);
}

Some of the examples have a showExternalLinks method that uses code similar to this. See, for example, JAXRSearchByName.java in the directory <INSTALL>/registry/samples/search-name/src.
