 org.xmpp.packet.PacketExtension
All known Subclasses: org.jivesoftware.openfire.sip.calllog.CallLogExtension, org.xmpp.forms.DataForm,
| PacketExtension | | public class PacketExtension (Code) | | A packet extension represents a child element of a Packet for a given qualified name. The
PacketExtension acts as a wrapper on a child element the same way Packet does for a whole
element. The wrapper provides an easy way to handle the packet extension.
Subclasses of this class can be registered using the static variable
registeredExtensions. The registration process associates the new subclass
with a given qualified name (ie. element name and namespace). This information will be used by
Packet.getExtension(StringString) for locating the corresponding PacketExtension
subclass to return for the requested qualified name. Each PacketExtension must have a public
constructor that takes an Element instance as an argument.
