public ByteBuf order(java.nio.ByteOrder endianness)
Description copied from class:ByteBufReturns a buffer with the specifiedendiannesswhich shares the whole region, indexes, and marks of this buffer. Modifying the content, the indexes, or the marks of the returned buffer or this buffer affects each other's content, indexes, and marks.

slice
public ByteBuf slice()
Description copied from class:ByteBufReturns a slice of this buffer's readable bytes. Modifying the content of the returned buffer or this buffer affects each other's content while they maintain separate indexes and marks. This method is identical tobuf.slice(buf.readerIndex(), buf.readableBytes()). This method does not modifyreaderIndexorwriterIndexof this buffer.Also be aware that this method will NOT call
