public class ZipSymbolicLinkEntry
extends ZipEntry
implements ArchiveSymbolicLinkEntry<ZipEntry,ZipDirectoryEntry>

This object represents a symbolic link entry in a Zip archive. In addition to the properties inherited from ZipEntry, a symbolic link has a link target and a CRC 32 checksum calculated on the link value.

Zip entries are always immutable.
