  • public final class HeapBufferIterator
extends BufferIterator
    Iterates over big- or little-endian bytes in a Java byte[].

      Modifier and Type Method Description
      static BufferIterator iterator​(byte[] buffer, int offset, int byteCount, ByteOrder order)
      Returns a new iterator over buffer, starting at offset and continuing for byteCount bytes.
      byte readByte()
      Returns the byte at the current position, and advances the current position one byte.
      void readByteArray​(byte[] dst, int dstOffset, int byteCount)
      Copies byteCount bytes from the current position into dst, starting at dstOffset, and advances the current position byteCount bytes.
      int readInt()
      Returns the 32-bit int at the current position, and advances the current position four bytes.
      void readIntArray​(int[] dst, int dstOffset, int intCount)
      Copies intCount 32-bit ints from the current position into dst, starting at dstOffset, and advances the current position 4 * intCount bytes.
      short readShort()
      Returns the 16-bit short at the current position, and advances the current position two bytes.
      void seek​(int offset)
      Seeks to the absolute position offset, measured in bytes from the start.
      void skip​(int byteCount)
      Skips forwards or backwards byteCount bytes from the current position.
