public ReceiverAdapter()
Method Detail

receive

public void receive(Message msg)
Description copied from interface: MessageListener
Called when a message is received.

Specified by:
receive in interface MessageListener

getState

public byte[] getState()
Description copied from interface: MessageListener
Answers the group state; e.g., when joining.

Specified by:
getState in interface MessageListener
Returns:
byte[]

setState

public void setState(byte[] state)
Description copied from interface: MessageListener
Sets the group state; e.g., when joining.

Specified by:
setState in interface MessageListener

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.

Specified by:
viewAccepted in interface MembershipListener

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.

Specified by:
suspect in interface MembershipListener

block

public void block()
Description copied from interface: MembershipListener
Called (usually by the FLUSH protocol), as an indication that the member should stop sending messages. Any messages sent after returning from this callback might get blocked by the FLUSH protocol. When the FLUSH protocol is done, and messages can be sent again, the FLUSH protocol will simply unblock all pending messages. If a callback for unblocking is desired, implement ExtendedMembershipListener.unblock(). Note that block() is the equivalent of reception of a BlockEvent in the pull mode.

Specified by:
block in interface MembershipListener
