Class RequestStatusMessage

java.lang.Object

org.sim0mq.message.Sim0MQMessage

org.sim0mq.message.federatestarter.RequestStatusMessage

All Implemented Interfaces:

Serializable

public class RequestStatusMessage
extends Sim0MQMessage

RequestStatus, FS.1. This message is sent by the Federate Starter to the Model until a "started" response is received from the Model. Since the message type id clarifies the function of this message and no information exchange is necessary, the payload field can be empty (number of fields = 0).

Constructor Detail

RequestStatusMessage

public RequestStatusMessage(Object simulationRunId,
                            Object senderId,
                            Object receiverId,
                            long messageId)
                     throws Sim0MQException,
                            NullPointerException

Parameters:

simulationRunId - the Simulation run ids can be provided in 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
