    • getConfigResource

      @Deprecated(forRemoval=true) public Resource getConfigResource()
      Deprecated, for removal: This API element is subject to removal in a future version.
      Returns:
      the resource associated with the configured properties file, creating it if necessary

    • isHotReload

      Deprecated.
      use getReloadInterval()
      Is hot reload enabled on this user store
      Returns:
      true if hot reload was enabled before startup

    • setHotReload

      @Deprecated public void setHotReload(boolean enable)
      Deprecated.
      use setReloadInterval(int)
      Enable Hot Reload of the Property File
      Parameters:
      enable - true to enable to a 1 second scan, false to disable

    • setReloadInterval

      public void setReloadInterval(int scanSeconds)
      Enable Hot Reload of the Property File
      Parameters:
      scanSeconds - the period in seconds to scan for property file changes, or 0 for no scanning

    • getReloadInterval

      public int getReloadInterval()
      Get the period in seconds to scan for property file changes, or 0 for no scanning.
      Returns:
      the period in seconds to scan for property file changes, or 0 for no scanning

    • toString

      public String toString()

      IOException - If the users cannot be loaded

    • doStart

      protected void doStart() throws Exception
      Depending on the value of the refresh interval, this method will either start up a scanner thread that will monitor the properties file for changes after it has initially loaded it. Otherwise the users will be loaded and there will be no active monitoring thread so changes will not be detected.
