public interface DAOPlugin

Common parent interface for various DAO plugin subinterfaces. You cannot write a plugin, which implements only this interface - it is abstract. Instead, a plugin implementation must implement one or more of the derived from this definition subinterfaces. Depending on what particular subinterfaces your plugin implements, the DAO will be calling its methods at certain moments to perform certain elementary operations.

To install a plugin add a <plugin> element into your DAO configuration in the blo-config.xml file:

 <plugin>
   <class>org.myorganization.myapplication.MyDAOPluginImplementation</class>
 </plugin>

Note, that some subinterfaces allow to have multiple plugins implementing them installed on a DAO, while others allow only one single plugin of that type for a DAO.
