  • Field Details

    • READ_ONLY_SYNC

      public static final FileChannel.MapMode READ_ONLY_SYNC
      File mapping mode for a read-only mapping of a file backed by non-volatile RAM.

      The map method throws UnsupportedOperationException when this map mode is used on an implementation that does not support it.

      Implementation Note:
      On Linux, the MAP_SYNC and MAP_SHARED_VALIDATE flags are specified to mmap when mapping the file into memory.

    • READ_WRITE_SYNC

      public static final FileChannel.MapMode READ_WRITE_SYNC
      File mapping mode for a read-write mapping of a file backed by non-volatile RAM. force operations on a buffer created with this mode will be performed using cache line writeback rather than proceeding via a file device flush.

      The map method throws UnsupportedOperationException when this map mode is used on an implementation that does not support it.

      Implementation Note:
      On Linux, the MAP_SYNC and MAP_SHARED_VALIDATE flags are specified to mmap when mapping the file into memory.
