com.audium.core.vfc.list.VList. This class is used to encapsulate a list of items that can be
deployed as either a traverse list or a streaming list. A traverse list presents a menu after an
item is presented that allows the caller to move forwards and backwards through the list. A
streaming list is one where all the items are played one after the other. This VFC class does
not reflect any VoiceXML tags, it was produced by Cisco Unified CVP to facilitate the
creation of lists within VoiceXML. The class outputs a set of forms that implement the list.
Form Items. VForm classes encapsulate most of the content of a VoiceXML page, and each
form has any number of form items added to it. These form items span the range of capturing
input from the caller to performing a telephony transfer. Each form item has a different
purpose, though many form items share features in common. The VFCs relate the classes that
handle each form item by creating a hierarchy starting with the simplest form items, with
features common to all, to more complex form items that add features through each
successive class extension. Figure 15-2 shows this class hierarchy and a description of each
branch is listed below.
