本文整理了Java中ch.qos.logback.core.util.FileSize类的一些代码示例，展示了FileSize类的具体用法。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。FileSize类的具体详情如下：
包路径：ch.qos.logback.core.util.FileSize
类名称：FileSize

FileSize介绍

[英]Instances of this class represent the size of a file. Internally, the size is stored as long.

The #valueOf method can convert strings such as "3 kb", "5 mb", into FileSize instances. The recognized unit specifications for file size are the "kb", "mb", and "gb". The unit name may be followed by an "s". Thus, "2 kbs" and "2 kb" are equivalent. In the absence of a time unit specification, byte is assumed.
[中]此类的实例表示文件的大小。在内部，大小存储为long。
#valueOf方法可以将诸如“3KB”、“5MB”之类的字符串转换为文件大小的实例。公认的文件大小单位规格为“kb”、“mb”和“gb”。装置名称后面可以跟一个“s”。因此，“2kb”和“2kb”是等价的。在没有时间单位规范的情况下，假定为字节。
