如何使用TrueZip获取档案中文件的大小? [英] How can you get the size of a file in an archive using TrueZip?

问题描述

根据TrueZip文档，length()方法似乎返回0或-1. 我正在更新WAR存档，我只想更新其长度已更改的文件.如何实现?

As per the TrueZip docs, it appears that the length() method returns 0 or -1. I am updating a WAR archive and I would like to only update files whose lengths have changed. How can this be achieved?

预先感谢

推荐答案

首先，调用方法TFile.umount()提交所有更改.

First, call the method TFile.umount() to commit any changes.

然后使用以下方法获取未检测到存档文件的TFile并调用其length()方法:

Then use the following method to obtain a TFile which does not detect the archive file and call its length() method:

private static TFile newNonArchiveFile(TFile file) {
    return new TFile(file.getParentFile(), file.getName(), TArchiveDetector.NULL);
}
