  • Method Details

    • getVersion

      long getVersion()
      During runtime, it's guaranteed that version for one configuration never decreases. Therefore clients, whose results depend on more configurations can use sum of their versions as the timestamp.
      Returns:
      The version number of this data.

    • getData

      Object getData()
      Returns:
      The data as produced by the IDataHandler.

    • getRevision

      long getRevision()
      This is the last repository revision for current configuration. Revision is calculated through all of the possible configuration locations. If revisions of two IConfig instances are different, then configurations are different, but not vice versa.
      Returns:
      last repository revision, or -1 if configuration does not exist.
