示例1: getUnadjustedFrameLength
import io.netty.buffer.ByteBuf; //导入方法依赖的package包/类
/**
* Decodes the specified region of the buffer into an unadjusted frame length. The default implementation is
* capable of decoding the specified region into an unsigned 8/16/24/32/64 bit integer. Override this method to
* decode the length field encoded differently. Note that this method must not modify the state of the specified
* buffer (e.g. {@code readerIndex}, {@code writerIndex}, and the content of the buffer.)
*
* @throws DecoderException
* if failed to decode the specified region
