Message.getSeqnum

Retrieve the sequence number of a message.

Messages have ever-incrementing sequence numbers, which may also be set explicitly via Message.setSeqnum. Sequence numbers are typically used to indicate that a message corresponds to some other set of messages or events, for example a SEGMENT_DONE message corresponding to a SEEK event. It is considered good practice to make this correspondence when possible, though it is not required.

Note that events and messages share the same sequence number incrementor; two events or messages will never have the same sequence number unless that correspondence was made explicitly.
