viewAccepted

public void viewAccepted(View new_view)
Description copied from interface: MembershipListener
Called when a change in membership has occurred. No long running actions should be done in this callback. If some long running action needs to be performed, it should be done in a separate thread.

suspect

public void suspect(Address suspected_mbr)
Description copied from interface: MembershipListener
Called whenever a member is suspected of having crashed, but has not yet been excluded.

block

public void block()
Description copied from interface: MembershipListener
Called whenever the member needs to stop sending messages. When the next view is received (viewAccepted()), the member can resume sending messages. If a member does not comply, the message(s) sent between a block() and a matching viewAccepted() callback will probably be delivered in the next view. The block() callback is only needed by the Virtual Synchrony suite of protocols (FLUSH protocol)3.2, otherwise it will never be invoked.

Specified by:
block in interface MembershipListener
