Class TransactionIDGenerator

  +--at.gv.egovernment.moa.spss.server.transaction.TransactionIDGenerator

public class TransactionIDGenerator

extends Object

A generator for unique transaction IDs.

The transaction IDs are of the form "-", where:

• base is initialized with the system time when this class is being loaded
• counter is incremented sequentially on each call to nextID()

Assuming that it is highly unlikely that MOA servers are started at exactly the same time instant, the mechanism provided by this class should guarantee unique transaction IDs across multiple restarts and/or instances of the server.
