'Package' of event handlers... @author Geir Magnusson Jr. @author Jose Alberto Fernandez @version $Id: EventCartridge.java,v 1.3.4.1 2004/03/03 23:22:53 geirm Exp $
org.apache.velocity.app.event.EventCartridge
Stores the event handlers. Event handlers can be assigned on a per VelocityEngine instance basis by specifying the class names in the velocity.properties file. Event handlers may also be assigned on a per-page basis by creating a new instance of EventCartridge, adding the event handlers, and then calling attachToContext. For clarity, it's recommended that one approach or the other be followed, as the second method is primarily presented for backwards compatibility.
Note that Event Handlers follow a filter pattern, with multiple event handlers allowed for each event. When the appropriate event occurs, all the appropriate event handlers are called in the sequence they were added to the Event Cartridge. See the javadocs of the specific event handler interfaces for more details. @author Will Glass-Husain @author Geir Magnusson Jr. @author Jose Alberto Fernandez @version $Id: EventCartridge.java 292972 2005-10-01 12:36:19Z henning $
