示例1: decodeCopyWith2ByteOffset
import io.netty.buffer.ByteBufUtil; //导入方法依赖的package包/类
/**
* Reads a compressed reference offset and length from the supplied input
* buffer, seeks back to the appropriate place in the input buffer and
* writes the found data to the supplied output stream.
*
* @param tag The tag used to identify this as a copy is also used to encode
* the length and part of the offset
* @param in The input buffer to read from
* @param out The output buffer to write to
* @throws DecompressionException If the read offset is invalid
* @return The number of bytes appended to the output buffer, or -1 to indicate
* "try again later"
