本文整理了Java中io.netty.buffer.ByteBuf.writeShort()方法的一些代码示例，展示了ByteBuf.writeShort()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ByteBuf.writeShort()方法的具体详情如下：
包路径：io.netty.buffer.ByteBuf
类名称：ByteBuf
方法名：writeShort

ByteBuf.writeShort介绍

[英]Sets the specified 16-bit short integer at the current writerIndex and increases the writerIndex by 2in this buffer. The 16 high-order bits of the specified value are ignored.
[中]在当前writerIndex处设置指定的16位短整数，并在此缓冲区中将writerIndex增加2。指定值的16个高位将被忽略。
