public class MessagingTask
extends GenericMessagingTask<java.lang.Integer,java.lang.Object>

Author:

V. Arun This messaging task means that each msg needs to be sent to all recipients. Note: it does *NOT* mean that each msg needs to be sent to its corresponding recipient; in fact, the sizes of the two arrays, recipients and msgs, may be different. This is a utility class as it is really just a container for two arrays.

MessagingTask

public MessagingTask(int[] destIDs,
                     java.lang.Object[] pkts)

Multicast multiple packets. This is a special type of constructor compared to the others above. This is the only constructor that allows MessagingTask to be instantiated with no messages. We need this as it is convenient to create an empty MessagingTask in a logging-only LogMessagingTask object.

Parameters:

destIDs -

pkts -
