CHAPTER 13: LOGGERS VOICEXML PROGRAMMING GUIDE

FOR CISCO UNIFIED CUSTOMER VOICE PORTAL RELEASE 4.0(1)

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:

Figure 13-1

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).
