Examples of org.apache.vysper.xmpp.protocol.StanzaHandler

org.apache.vysper.xmpp.protocol.StanzaHandler
While stanzas hold the raw information read from stream, its handler holds the logic for interpreting its semantics and execution. If stanzas are commands, a StanzaHandler is a command processor. It is very much comparable to a Servlet. StanzaHandler implementations must be stateless! @author The Apache MINA Project (dev@mina.apache.org)
