  • Method Details

    • readMoreInput

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

      Should not be called 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.

    • checkHealth

      static int 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 int initBitReader(State s)

    • prepare

      private static int prepare(State s)

    • reload

      static int reload(State s)

    • jumpToByteBoundary

      static int jumpToByteBoundary(State s)

    • halfAvailable

      static int halfAvailable(State s)

    • copyRawBytes

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

    • bytesToNibbles

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