public class DatabaseList

extends Object

implements GadgetBuilder

The DatabaseList class is a gadget that builds an HTML String containing a list of anchors containing database names that a user has access to. It uses the parameters contained in a RequestManager object and the parameters for the gadget read from the configuration files to build the appropriate output. If an error occurs, an empty string("") is returned.

The parameters to the gadget are:
anchorcommand - the URL command action to put in the anchor.
dbnames - a comma space separated list of dbnames to build the list from. If ommitted, all databases the user has access to is built.

For efficiency purposes, the database list string is generated for a user only if it does not exist. The formatted string is stored in the user state as the entity named DatabaseList. Each subsequent request for the data is simply a retrieval from the user state for the saved string.
