  • Method Details

    • prepareClose

      default void prepareClose()
      prepare for closing this object that implements Closeable. This is the first part of the closing process. As a object may need database access to close cleanly this method can be used to be ahead of database outtake.

    • close

      void close()
      cleanly closes this object that implements Closeable. You can provide some functionality to close open files and sockets or so.

    • getPriority

      default int getPriority()
      Returns the priority. A Closeable with a higher priority will be closed before a Closeable with a lower priority. Default priority is 5.

    • compareTo

      default int compareTo(MCRShutdownHandler.Closeable other)
      Specified by:
      compareTo in interface Comparable<MCRShutdownHandler.Closeable>
