Class PduStream

  edu.nps.moves.sql.PduStream

@Entity
public class PduStream
extends java.lang.Object

Describes one stream of PDUs. If we're staving PDUs from the network into a database, one danger is that we put data from several exercises into a single table. There would be no way to tell which PDUs came from what exercise. (Theoretically the exerciseID could be used for this, but it wouldn't work well for various reasons.)

The PDU stream has an identifier which can be used as a foreign key in the PDU header, via a special, non-DIS addition to the PDU header that is not marshalled to IEEE packets. This ID refers to an entry in this table, which describes the name of the stream being recorded, the start time (in local wall clock time) and the end time (ditto). With this information you can extract all the PDUs related to the exercise from the table of PDUs, once you select the PDU stream from this table.
