  • Method Details

    • refresh

      public static void refresh()

      Can refresh the timezone cache in case of a dynamic update of the underlying timezone repository.

      First the internal cache will be cleared. Furthermore, if needed the system timezone will be determined again.

    • setCacheActive

      public static void setCacheActive​(boolean active)

      Aktivates or deactivates the internal cache.

      The timezone cache is active by default. Switching off the cache can make the performance worse especially if the underlying ZoneModelProvider itself has no cache.

      Parameters:
      active - true if cache shall be active else false

    • setMinimumCacheSize

      public static void setMinimumCacheSize​(int minimumCacheSize)

      Updates the size of the internal timezone cache.

      Parameters:
      minimumCacheSize - new minimum size of cache
      Throws:
      IllegalArgumentException - if the argument is negative
