Constructor Detail

HB1HeartbeatMessage

public HB1HeartbeatMessage(Object federationId,
                           Object senderId,
                           Object receiverId,
                           Object messageId)
                    throws Sim0MQException,
                           NullPointerException

Parameters:

federationId - the federation id can be coded using different types. Examples are two 64-bit longs indicating a UUID, or a String with a UUID number, a String with meaningful identification, or a short or an int with a simulation run number.

senderId - The sender id can be used to send back a message to the sender at some later time.

receiverId - The receiver id can be used to check whether the message is meant for us, or should be discarded (or an error can be sent if we receive a message not meant for us).

messageId - The unique message number is meant to confirm with a callback that the message has been received correctly. The number is unique for the sender, so not globally within the federation.

Throws:

Sim0MQException - on unknown data type

NullPointerException - when one of the parameters is null
