本文整理了Java中com.google.common.hash.HashCode.fromString()方法的一些代码示例，展示了HashCode.fromString()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。HashCode.fromString()方法的具体详情如下：
包路径：com.google.common.hash.HashCode
类名称：HashCode
方法名：fromString

HashCode.fromString介绍

[英]Creates a HashCode from a hexadecimal ( base 16) encoded string. The string must be at least 2 characters long, and contain only valid, lower-cased hexadecimal characters.

This method accepts the exact format generated by #toString. If you require more lenient base 16 decoding, please use com.google.common.io.BaseEncoding#decode(and pass the result to #fromBytes).
[中]从十六进制（以16为基数）编码的字符串创建哈希代码。字符串长度必须至少为2个字符，并且仅包含有效的小写十六进制字符。
此方法接受#toString生成的精确格式。如果您需要更宽松的base 16解码，请使用com。谷歌。常见的木卫一。BaseEncoding#解码（并将结果传递给#fromBytes）。
