docs: Compare <code>dataIds</code> against each other. The user <b>must not compare these ids</b> with built-in comparison
  operators. These ids wrap around to their {@link Short#MIN_VALUE min value} once they are incremented beyond
  their {@link Short#MAX_VALUE max value}, hence this compare method must be used.
  @param dataId1 the first id to compare
  @param dataId2 the second id to compare
