Class DefaultEventConverter
java.lang.Object
org.apache.avalon.framework.logger.AbstractLogEnabled
org.apache.cocoon.portal.impl.AbstractComponent
org.apache.cocoon.portal.event.impl.DefaultEventConverter
- All Implemented Interfaces:
- Configurable, Contextualizable, Disposable, EventConverter, Initializable, LogEnabled, Serviceable, ThreadSafe
- public class DefaultEventConverter
- extends AbstractComponent
- implements EventConverter, Configurable
This implementation stores the events that can't be converted to strings (which don't
support the ConvertableEvent
interface) in
the current user session. Each event is then converted to a string just containing
the index of the event in this list. This list is cleared when the session is closed.
TODO - What happens if two event classes have the same hash?

EVENT_LIST
protected static final String EVENT_LIST
factories
protected Map factories
- All factories mapped by a key.
The key is either the hash if the class name or a configured mapping.
If there is no configured mapping for an event class, the value
is the constructor to construct the event.
If there is a configured mapping, then this map contains two entries:
The first entry has the hash of the class name as the key and the value
is the configured mapping name. The second entry has the configured mapping
name as the key and the Constructor as the value.
