示例1: writeVLong
import io.netty.buffer.DrillBuf; //导入方法依赖的package包/类
/**
* Serializes a long to a binary stream with zero-compressed encoding.
* For -112 <= i <= 127, only one byte is used with the actual value.
* For other values of i, the first byte value indicates whether the
* long is positive or negative, and the number of bytes that follow.
* If the first byte value v is between -113 and -120, the following long
* is positive, with number of bytes that follow are -(v+112).
* If the first byte value v is between -121 and -128, the following long
* is negative, with number of bytes that follow are -(v+120). Bytes are
* stored in the high-non-zero-byte-first order.
*
* @param buffer DrillBuf to write to
* @param i Long to be serialized
