This method is the execution method for the logger and is called by Unified CVP VoiceXML 
Server when a new event has occurred that the logger must handle. This method is called only if 
the VoiceXML Server has found the event’s ID in the 

eventsToListenFor HashSet

. 

Only one object is passed to this method, an 

ApplicationEvent

. This object encapsulates all the 

information about the event and provides access to other environment information depending on 
the type of event. 

ApplicationEvent

 is a base class for all application-level events and the 

logger will typically check for the event type and cast to the appropriate event to get its 
information. All event classes are found in the 

com.audium.server.logger.events

 package. 

Figure 13-1 shows the class hierarchy for all events: 

 

Notes on events: 

   

ApplicationEvent

 is currently the only event that extends the generic event class 

LoggerEvent

. This structure is designed to support additional event types in the future 

without affecting the existing class hierarchy. 

    All events have an ID, obtained by calling the 

getID

 method. All application events have 

access to the Global API to get application and global data (see the VoiceXML Server User 
Guide for Cisco Unified Customer Voice Portal Chapter 2 in the section entitled Variables 
for more on application and global data).
