        Specified by:
        arrayOffset in interface Buffer
        Returns:
        the offset in the array.

      • toString

        public java.lang.String toString​(java.nio.charset.Charset charset)
        Description copied from interface: Buffer
        Decodes this buffer's readable bytes into a string with the specified character set name. This method is identical to buf.toString(buf.readerIndex(), buf.readableBytes(), charsetName). This method does not modify readerIndex or writerIndex of this buffer.
        Specified by:
        toString in interface Buffer
        Parameters:
        charset - the charset to use.
        Returns:
        the string.

        public java.lang.String toString​(int index,
                                 int length,
                                 java.nio.charset.Charset charset)
        Description copied from interface: Buffer
        Decodes this buffer's sub-region into a string with the specified character set. This method does not modify readerIndex or writerIndex of this buffer.
        Specified by:
        toString in interface Buffer
        Parameters:
        index - the start index.
        length - the length.
        charset - the charset to use.
        Returns:
        the string.

      • forEachByte

        public int forEachByte​(ByteProcessor processor)
        Description copied from interface: Buffer
        Iterates over the readable bytes of this buffer with the specified processor in ascending order.
        Specified by:
        forEachByte in interface Buffer
        Parameters:
        processor - the ByteProcessor to use.
        Returns:
        -1 if the processor iterated to or beyond the end of the readable bytes. The last-visited index If the ByteProcessor.process(byte) returned false.

      • forEachByte

        public int forEachByte​(int index,
                       int length,
                       ByteProcessor processor)
        Description copied from interface: Buffer
        Iterates over the specified area of this buffer with the specified processor in ascending order. (i.e. index, (index + 1), .. (index + length - 1))
        Specified by:
        forEachByte in interface Buffer
        Parameters:
        index - The index to start iterating from.
        length - The amount of bytes to iterate over.
        processor - the ByteProcessor to use.
        Returns:
        -1 if the processor iterated to or beyond the end of the specified area. The last-visited index If the ByteProcessor.process(byte) returned false.

      • forEachByteDesc

        public int forEachByteDesc​(ByteProcessor processor)
        Description copied from interface: Buffer
        Iterates over the readable bytes of this buffer with the specified processor in descending order.
        Specified by:
        forEachByteDesc in interface Buffer
        Parameters:
        processor - the ByteProcessor to use.
        Returns:
