  • Method Details

    • readMoreInput

      static void readMoreInput(State s)
      Fills up the input buffer.

      No-op if there are at least 36 bytes present after current position.

      After encountering the end of the input stream, 64 additional zero bytes are copied to the buffer.

    • doReadMoreInput

      static void doReadMoreInput(State s)

    • checkHealth

      static void checkHealth(State s, int endOfStream)

    • assertAccumulatorHealthy

      static void assertAccumulatorHealthy(State s)

    • fillBitWindow

      static void fillBitWindow(State s)

    • doFillBitWindow

      static void doFillBitWindow(State s)

    • peekBits

      static int peekBits(State s)

    • readFewBits

      static int readFewBits(State s, int n)
      Fetches bits from accumulator. WARNING: accumulator MUST contain at least the specified amount of bits, otherwise BitReader will become broken.

    • readBits

      static int readBits(State s, int n)

    • readManyBits

      private static int readManyBits(State s, int n)

    • initBitReader

      static void initBitReader(State s)

    • prepare

      private static void prepare(State s)

    • reload

      static void reload(State s)

    • jumpToByteBoundary

      static void jumpToByteBoundary(State s)

    • halfAvailable

      static int halfAvailable(State s)

    • copyRawBytes

      static void copyRawBytes(State s, byte[] data, int offset, int length)

    • bytesToNibbles

      static void bytesToNibbles(State s, int byteLen)
      Translates bytes to halves (int/short).
