Class UnparseableExtraFieldData

  • All Implemented Interfaces:
    CentralDirectoryParsingZipExtraField, ZipExtraField

    public final class UnparseableExtraFieldData
    extends java.lang.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
