Constructor Detail

MC1StatusMessage

public MC1StatusMessage(Object simulationRunId,
                        Object senderId,
                        Object receiverId,
                        long messageId,
                        long uniqueId,
                        String status,
                        String error)
                 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.

uniqueId - Id to identify the callback to the message.

status - A string that refers to the model status. Four options: "started", "running", "ended", "error".

error - Optional. If there is an error, the error message is sent as well. Otherwise this field is an empty string.

Throws:

Sim0MQException - on unknown data type

NullPointerException - when one of the parameters is null
