Class GenerateATRIds

  • @Internal
public class GenerateATRIds
extends java.lang.Object
    A tool for internal use that generates the fixed ATR ids. Note the results are randomly generated and hence not idempotent. Regenerating these numbers will result in a transaction client that is not aware of, and hence cannot cleanup, ATRs from previous clients. E.g. it's No-No City.
