Method Detail

viewAccepted

public void viewAccepted(View new_view)
Called by JGroups to notify the target object of a change of membership. No long running actions should be done in this callback in the case of Ensemble, as this would block Ensemble. If some long running action needs to be performed, it should be done in a separate thread (cf. ../Tests/QuoteServer.java).


suspect

public void suspect(Address suspected_mbr)
Called when a member is suspected


block

public void block()
Block sending and receiving of messages until viewAccepted() is called
