public interface UnparseableExtraFieldBehavior {
    
Decides what to do with extra field data that doesn't follow the recommended pattern.

Params:
  • data – the array of extra field data
  • off – offset into data where the unparseable data starts
  • len – the length of unparseable data
  • local – whether the extra field data stems from the local
file header. If this is false then the data is part if the
central directory header extra data.
  • claimedLength – length of the extra field claimed by the
third and forth byte if it did follow the recommended pattern
Throws:
  • ZipException – if an error occurs or unparseable extra
fields must not be accepted
Returns:null if the data should be ignored or an extra field
implementation that represents the data
