public class DefaultPacketExtension extends Object implements PacketExtension
ProviderManager
,
instances of this class will be returned when getting packet extensions.This class provides a very simple representation of an XML sub-document. Each element is a key in a Map with its CDATA being the value. For example, given the following XML sub-document:
<foo xmlns="http://bar.com"> <color>blue</color> <food>pizza</food> </foo>In this case, getValue("color") would return "blue", and getValue("food") would return "pizza". This parsing mechanism mechanism is very simplistic and will not work as desired in all cases (for example, if some of the elements have attributes. In those cases, a custom PacketExtensionProvider should be used.
