本文整理了Java中io.vertx.core.buffer.Buffer.setByte()方法的一些代码示例,展示了Buffer.setByte()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。Buffer.setByte()方法的具体详情如下:
包路径:io.vertx.core.buffer.Buffer
类名称:Buffer
方法名:setByte

Buffer.setByte介绍

[英]Sets the byte at position pos in the Buffer to the value b.

The buffer will expand as necessary to accommodate any value written.
[中]将缓冲区中位置pos处的字节设置为值b。
缓冲区将根据需要扩展以容纳任何写入的值。

  assertEquals(i, buff.getByte(i));
