Class UnparseableExtraFieldData

java.lang.Object
org.apache.tools.zip.UnparseableExtraFieldData
All Implemented Interfaces:
CentralDirectoryParsingZipExtraField, ZipExtraField
public final class UnparseableExtraFieldData extends Object implements CentralDirectoryParsingZipExtraField
Wrapper for extra field data that doesn't conform to the recommended format of header-tag + size + data.

The header-id is artificial (and not listed as a known ID in APPNOTE.TXT). Since it isn't used anywhere except to satisfy the ZipExtraField contract it shouldn't matter anyway.

Since:
Ant 1.8.1
