Enum MappedByteBufferInputStream.CacheMode

    • Enum Constant Detail

      • FLUSH_PRE_SOFT

        public static final MappedByteBufferInputStream.CacheMode FLUSH_PRE_SOFT
        Soft flush the previous lazily cached buffer slice when caching the next buffer slice, useful for sequential forward readers, as well as for hopping readers like FLUSH_NONE in case of relatively short periods between hopping across slices.

        Implementation clears the buffer slice reference while preserving a WeakReference to allow its resurrection if not yet garbage collected.

      • FLUSH_PRE_HARD

        public static final MappedByteBufferInputStream.CacheMode FLUSH_PRE_HARD
        Hard flush the previous lazily cached buffer slice when caching the next buffer slice, useful for sequential forward readers.

        Besides clearing the buffer slice reference, implementation attempts to hard flush the mapped buffer using a sun.misc.Cleaner by reflection. In case such method does not exist nor works, implementation falls back to FLUSH_PRE_SOFT.

        This is the default.

      • values

        public static MappedByteBufferInputStream.CacheMode[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (MappedByteBufferInputStream.CacheMode c : MappedByteBufferInputStream.CacheMode.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static MappedByteBufferInputStream.CacheMode valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
