Examples of org.xmlBlaster.engine.admin.I_AdminSession

org.xmlBlaster.engine.admin.I_AdminSession
Declares available methods of a session for administration.
SNMP or telnet tools can access only the here declared properties.
This interface is implemented by SessionInfo.java, delivering the meat. @author xmlBlaster@marcelruff.info @since 0.79f
