InfoBus RowsetSource Demo

This page demonstrates RowsetSource (a data producer with no UI which can return RowsetAccess and ScrollableRowsetAccess items) and SampleConsumer (a data consumer which can watch for and dump data items.) You have to build the applets before they will run. For information, see the Read Me file.

RowsetSource maintains a tiny database containing tables named 'dept' and 'emp'. Upon startup, it announces the availability of data items named 'dept' and 'emp'. RowsetSource will return ScrollableRowset objects for these items if asked by a data consumer.

SampleConsumer watches for and dumps data items. In this example the SampleConsumer is setup to watch for the item named 'dept'. When 'dept' is announced the SampleConsumer finds and dumps it. You may also enter the name of a data item in the 'Get' text box and click on the GetData button to find and dump it. Only the checked interface types are dumped. There are only Rowset, ScrollableRowset and Immediate items in this example.
