Interface AgiDataSourceListener

public interface AgiDataSourceListener

Implemented by business objects with Data Source triggers. Business Objects that implement this interface 'listen' for Data Source events that occur on the Server. When the SilverStream Server receives such events, it passes an event object to all business objects 'listening' for events of that type.

When a Data Source object is created, SilverStream automatically adds the implements AgiDataSourceListener clause to the object's class definition.

Method Summary

void	invokeQuery(AgoDataSourceEvent e) Fires when a data source object receives a data request.
