      Modifier and Type Method Description
      byte[] array()
      Gets the backing array for this buffer.
      int arrayOffset()
      Gets the offset in the backing array of the current read position.
      boolean byteBufferSupported()
      Indicates whether or not ReadableBuffer.getByteBuffer() operation is supported for this buffer.
      java.nio.ByteBuffer getByteBuffer()
      Gets a ByteBuffer that contains some bytes of the content next to be read, or null if this buffer has been exhausted.
      boolean hasArray()
      Indicates whether or not this buffer exposes a backing array.
      void mark()
      Marks the current position in this buffer.
      boolean markSupported()
      Indicates whether or not ReadableBuffer.mark() operation is supported for this buffer.
      int readableBytes()
      Gets the current number of readable bytes remaining in this buffer.
      void readBytes​(byte[] dest, int destOffset, int length)
      Reads length bytes from this buffer and writes them to the destination array.
      ReadableBuffers.ByteReadableBufferWrapper readBytes​(int length)
      Reads length bytes from this buffer and returns a new Buffer containing them.
      void readBytes​(java.io.OutputStream dest, int length)
      Reads length bytes from this buffer and writes them to the destination stream.
      void readBytes​(java.nio.ByteBuffer dest)
      Reads from this buffer until the destination's position reaches its limit, and increases the read position by the number of the transferred bytes.
      int readUnsignedByte()
      Reads the next unsigned byte from this buffer and increments the read position by 1.
      void reset()
      Repositions this buffer to the position at the time ReadableBuffer.mark() was last called on this buffer.
      void skipBytes​(int length)
      Increments the read position by the given length.

      • readableBytes

        public int readableBytes()
        Description copied from interface: ReadableBuffer
        Gets the current number of readable bytes remaining in this buffer.
      • readUnsignedByte

        public int readUnsignedByte()
        Description copied from interface: ReadableBuffer
        Reads the next unsigned byte from this buffer and increments the read position by 1.
      • skipBytes

        public void skipBytes​(int length)
        Description copied from interface: ReadableBuffer
        Increments the read position by the given length.
      • readBytes

        public void readBytes​(byte[] dest,
                              int destOffset,
                              int length)
        Description copied from interface: ReadableBuffer
        Reads length bytes from this buffer and writes them to the destination array. Increments the read position by length.
        Parameters:
        dest - the destination array to receive the bytes.
        destOffset - the starting offset in the destination array.
        length - the number of bytes to be copied.
      • readBytes

        public void readBytes​(java.nio.ByteBuffer dest)
        Description copied from interface: ReadableBuffer
        Reads from this buffer until the destination's position reaches its limit, and increases the read position by the number of the transferred bytes.
        Parameters:
        dest - the destination buffer to receive the bytes.
      • readBytes

        public void readBytes​(java.io.OutputStream dest,
                              int length)
                       throws java.io.IOException
        Description copied from interface: ReadableBuffer
        Reads length bytes from this buffer and writes them to the destination stream. Increments the read position by length. If the required bytes are not readable, throws IndexOutOfBoundsException.
        Parameters:
        dest - the destination stream to receive the bytes.
        length - the number of bytes to be copied.
        Throws:
        java.io.IOException - thrown if any error was encountered while writing to the stream.
      • readBytes

        public ReadableBuffers.ByteReadableBufferWrapper readBytes​(int length)
        Description copied from interface: ReadableBuffer
        Reads length bytes from this buffer and returns a new Buffer containing them. Some implementations may return a Buffer sharing the backing memory with this buffer to prevent copying. However, that means that the returned buffer may keep the (possibly much larger) backing memory in use even after this buffer is closed.
        Parameters:
        length - the number of bytes to contain in returned Buffer.
      • getByteBuffer

        public java.nio.ByteBuffer getByteBuffer()
        Description copied from interface: ReadableBuffer
        Gets a ByteBuffer that contains some bytes of the content next to be read, or null if this buffer has been exhausted. The number of bytes contained in the returned buffer is implementation specific. The position of this buffer is unchanged after calling this method. The returned buffer's content should not be modified, but the position, limit, and mark may be changed. Operations for changing the position, limit, and mark of the returned buffer does not affect the position, limit, and mark of this buffer. Buffers returned by this method have independent position, limit and mark. This is an optional method, so callers should first check ReadableBuffer.byteBufferSupported().
