org.apache.tools.zip.UnrecognizedExtraField

All Implemented Interfaces:
  `CentralDirectoryParsingZipExtraField`, `ZipExtraField`

    public class UnrecognizedExtraField
    extends java.lang.Object
    implements CentralDirectoryParsingZipExtraField

Simple placeholder for all those extra fields we don't want to deal with.

Assumes local file data and central directory entries are identical - unless told the opposite.
