Method Detail

retransmit

public void retransmit(long first_seqno,
                       long last_seqno,
                       Address sender)

Parameters:
first_seqno - The sequence number of the first missing message
last_seqno - The sequence number of the last missing message
sender - The destination of the member to which the retransmit request will be sent (nak-based scheme), or to which the message will be retransmitted (ack-based scheme).
