  +--org.jafer.zclient.Session

public class Session

extends java.lang.Object

Manages a zclient session and sets up connection with zserver using org.jafer.util.PDUDriver. A session can be anonymous or if authentication is required by target, the client sets properties for user/group/password. Changing these properties will terminate an existing session and establish a new one.
