public class UIDOnlineManager extends Object implements UIDManager

  • Method Details

    • runStartupChecks

      public boolean runStartupChecks()
      Finds largest UID for each PamDataBlock. Originally this method came up with a list of all UIDs from the database, another list of all UIDs from the binary files, and then tried to match up the PamDataBlocks with both lists. That has been commented out now and reworked to loop through the PamDataBlocks first, and only search for UIDs specific to each block. The original code was working, and therefore only commented out and not deleted in case we need to go back to it.
      Specified by:
      runStartupChecks in interface UIDManager
      Returns:
      true if all checks completed successfully.

    • synchUIDs

      public void synchUIDs(boolean onlyNewDataBlocks)
      Loop through the data blocks and try to find matching database and binary file UID information. Assign the highest UID value found to the data block. If the onlyNewDataBlocks flag is true, only perform this operation on data blocks which have a current UID of 0 (which will happen if the module has just been added).

      synchUIDs in interface UIDManager
