  • Method Details

    • close

      default void close()
      Called when the region containing this callback is closed or destroyed, when the cache is closed, or when a callback is removed from a region using an AttributesMutator.

      Implementations should cleanup any external resources such as database connections. Any runtime exceptions this method throws will be logged.

      It is possible for this method to be called multiple times on a single callback instance, so implementations must be tolerant of this.
