HandleXMLTask

public HandleXMLTask(java.util.Map outgoing_sockets,
                     java.net.Socket incoming_socket,
                     WrappedInputStream wrapped_in,
                     java.util.Map incoming_names,
                     java.util.Collection outside_connects,
                     LDAPCommunicator ldap_communicator,
                     Logger log,
                     Document doc,
                     java.util.Map object_streams,
                     java.util.Map return_streams)

Constructor, This takes a socket and a map of PServer to MDS sockets and handles tasks coming from the outside (e.g. PServer/PClient connections tasks) if the socket has been authenticated

Parameters:

outgoing_sockets - the map of PServer to MDS

incoming_socket - the socket that needs a task done

incoming_names - the map of sockets connections to usernames

ldap_communicator - Handles communication with LDAP server

log - Logs events

HandleXMLTask

public HandleXMLTask(java.net.Socket new_socket,
                     java.util.Map outgoing_sockets,
                     java.util.Collection outside_connects,

                     AddressPort inet_sock,
                     java.util.Map return_streams)

Constructor, This takes a new socket, a map of PServer to MDS sockets and a List of active sockets and handles tasks coming from the outside (e.g. PServer/PClient connections tasks).

Parameters:

new_socket - the socket that needs a task done

outgoing_sockets - the map of PServer to MDS

outside_connects - List of active authenticated sockets

incoming_names - the map of sockets connections to usernames

ldap_communicator - Handles communication with LDAP server

log - Logs events

inet_sock - The socket address of the MDSProxy server socket
