Interface MssUser

All Known Implementing Classes:

Daemon

public interface MssUser

The MssUser interface should be implemented by layers using the Mss to receive callback notifications from the Mss itself.

Since:

Jgroup 0.1

Author:

Alberto Montresor

Method Summary

void	localReceive(Event upcall) Invoked to notify the objects implementing this interface that a message from a local member has been received.
void	localSuspect(MemberId membId) Invoked to notify the objects implementing this interface that a remote object is not responding to remote method invocations, and thus should be crashed.
void	remoteReceive(byte tag, InMessage data, EndPoint host) Invoked to notify the objects implementing this interface that a message from a remote member has been received.
void	remoteSuspect(EndPoint[] rset, EndPoint[] nrset, EndPoint[] nuset, EndPoint[] newinc) Invoked to notify the objects implementing this interface that a variation in the perceived reachability set has been perceived.

Method Detail

remoteReceive

void remoteReceive(byte tag,
                   InMessage data,
                   EndPoint host)

Invoked to notify the objects implementing this interface that a message from a remote member has been received.

Parameters:

tag - the tag identifying the type of message

stream - the message, represented by a InMessage object

src - the sender of the message

localReceive

void localReceive(Event upcall)

Invoked to notify the objects implementing this interface that a message from a local member has been received.

Parameters:

event - represents the received message

remoteSuspect

void remoteSuspect(EndPoint[] rset,
                   EndPoint[] nrset,
                   EndPoint[] nuset,
                   EndPoint[] newinc)

Invoked to notify the objects implementing this interface that a variation in the perceived reachability set has been perceived.

Parameters:

trset - set of all (total) reachables hosts

nrset - set of reachable hosts that were unreachable

nuset - set of unreachable hosts that were reachable

newinc - set of hosts who has a new incarnation identifier

localSuspect

void localSuspect(MemberId membId)

Invoked to notify the objects implementing this interface that a remote object is not responding to remote method invocations, and thus should be crashed.

Parameters:

membId - a callback object identifying the suspected object; this object has been stored in the Mss through the addPingListener method invocation on the Mss.
