本文整理了Java中com.sun.jna.Native.toString()方法的一些代码示例,展示了Native.toString()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。Native.toString()方法的具体详情如下:
包路径:com.sun.jna.Native
类名称:Native
方法名:toString

Native.toString介绍

[英]Obtain a Java String from the given native byte array. If there is no NUL terminator, the String will comprise the entire array. If the system property jna.encoding is set, its value will override the platform default encoding (if supported).
[中]从给定的本机字节数组中获取Java字符串。如果没有NUL终止符,则字符串将构成整个数组。如果设置了系统属性jna.encoding,其值将覆盖平台默认编码(如果支持)。
