com.sh.common.zip.UnrecognizedExtraField

所有已实现的接口:

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.
