本文整理了Java中de.schlichtherle.truezip.zip.ZipOutputStream类的一些代码示例,展示了ZipOutputStream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。ZipOutputStream类的具体详情如下:
包路径:de.schlichtherle.truezip.zip.ZipOutputStream
类名称:ZipOutputStream

ZipOutputStream介绍

[英]Drop-in replacement for java.util.zip.ZipOutputStream.

This class starts writing ordinary ZIP32 File Format. It automatically adds ZIP64 extensions if required, i.e. if the file size exceeds 4GB or more than 65535 entries are written. This implies that the class may produce ZIP archive files which cannot be read by older ZIP implementations.

If the system property de.schlichtherle.truezip.io.zip.zip64extis set to true (case is ignored), then ZIP64 extensions are always added when writing a ZIP archive file, regardless of its size. This system property is primarily intended for unit testing purposes. During normal operations, it should not be set as many third party tools would not treat the redundant ZIP64 extensions correctly. Note that it's impossible to inhibit ZIP64 extensions.

This class provides some limited support for multithreading: You can read its properties from multiple threads, but obviously you cannot concurrently write multiple entries at the same time by different threads.
[中]作为java的替代品。util。拉链ZipOutputStream。
这个类开始编写普通的ZIP32文件格式。如果需要,即文件大小超过4GB或写入的条目超过65535条,它会自动添加ZIP64扩展名。这意味着该类可能会生成旧的ZIP实现无法读取的ZIP存档文件。
如果系统属性为de.schlichtherle。特鲁齐普。伊奥。拉链Zip64ext设置为true(忽略大小写),那么在编写ZIP存档文件时,无论其大小,都会添加ZIP64扩展名。此系统属性主要用于单元测试目的。在正常操作过程中,不应设置它,因为许多第三方工具无法正确处理冗余的ZIP64扩展。请注意,不可能禁止ZIP64扩展。
这个类为多线程提供了一些有限的支持:您可以从多个线程中读取它的属性,但显然不能由不同的线程同时写入多个条目。
