Class ReceivalCheck

java.lang.Object

final class ReceivalCheck

For performance reasons, only an identifying integer (4 bytes) is saved for each message for later comparison.

LOGGER

private static final java.util.logging.Logger LOGGER

Logger used to log and display information.

checkInterval

private static long checkInterval

Interval after which a check for lost messages is performed. If a message isn't received after twice this interval, it is considered as lost.

sentMessages

private static int sentMessages

Number of messages "sent" so far.

receivedMessages

private static int receivedMessages

Number of messages "received" so far.

notYetReceived

private static java.util.LinkedList<java.lang.Integer> notYetReceived

List with messages, that were "sent", but not "received" so far.

notYetReceivedLastly

private static java.lang.Integer[] notYetReceivedLastly

Messages, that were "sent" in the last interval, but haven't been "received" yet. Used to check whether any of these messages hasn't been "received" even after the next interval. In this case a message is considered as lost.
