Class ArchivEntry

java.lang.Object
clazzfish.monitor.util.ArchivEntry
public final class ArchivEntry extends Object
Unfortunately we can't extends URI because this is a final class. So now it is more or less implemented as URI wrapper and is intended for the use with zip and jar files to describe an entry inside an archive.

Historically some parts of this class were developed for a log browser for Log4J. Next it was part of the PatternTesting project. The facility to read (compressed) tar files (using org.apache.commons.compress.tar.*) was removed because we use it here only for zip and jar files.

This class is final because of performance reasons. If you need to derive it write a feature request.
