Class NestedZipFile

java.lang.Object

java.util.zip.ZipFile

clazzfish.monitor.util.NestedZipFile

All Implemented Interfaces:

Closeable, AutoCloseable

public final class NestedZipFile
extends ZipFile

This class provides more details about the underlying ZIP file as the original ZipFile class. E.g. it has a useful toString() implementation which gives you the name of the file. And it allows you to use nested ZIP files, e.g. ZIP files inside ZIP files.

Originally this class was part of the PatternTesting project.
