Field Detail

Method Detail

handleDownEvent

public boolean handleDownEvent(Event evt)

handleJoin

public abstract boolean handleJoin(Address mbr)

handleLeave

public abstract void handleLeave(Address mbr, boolean suspected)

handleMerge

public abstract View handleMerge(ViewId other_view, Vector other_members)

handleSuspect

public abstract void handleSuspect(Address mbr)

handleViewChange

public abstract void handleViewChange(ViewId new_view, Vector mbrs)

iWouldBeCoordinator

protected boolean iWouldBeCoordinator(Vector new_mbrs)

Returns potential coordinator based on lexicographic ordering of member addresses. Another approach would be to keep track of the primary partition and return the first member if we are the primary partition.

join

public abstract void join(Address mbr)

leave

public abstract void leave(Address mbr)

merge

public abstract void merge(Vector coords)

suspect

public abstract void suspect(Address mbr)

wrongMethod

protected void wrongMethod(String method_name)
