ZipEntry (Apache Ant API)

java.lang.Object
- java.util.zip.ZipEntry
- - org.apache.tools.zip.ZipEntry

All Implemented Interfaces:

java.lang.Cloneable
```
public class ZipEntry
extends java.util.zip.ZipEntry
implements java.lang.Cloneable
```
Extension that adds better handling of extra fields and provides access to the internal and external file attributes.
The extra data is expected to follow the recommendation of APPNOTE.txt:
- the extra byte array consists of a sequence of extra fields
- each extra fields starts by a two byte header id followed by a two byte sequence holding the length of the remainder of data.
Any extra data that cannot be parsed by the rules above will be consumed as "unparseable" extra data and treated differently by the methods of this class. Older versions would have thrown an exception if any attempt was made to read or write extra data not conforming to the recommendation.
