Interface ZipExtraField

  • 
public interface ZipExtraField

    General format of extra field data.

    Extra fields usually appear twice per file, once in the local file data and once in the central directory. Usually they are the same, but they don't have to be. java.util.zip.ZipOutputStream will only use the local file data in both places.

      abstract ZipShort getHeaderId() The Header-ID.
      abstract Array<byte> getLocalFileDataData() The actual data to put into local file data - without Header-IDor length specifier.
      abstract ZipShort getLocalFileDataLength() Length of the extra field in the local file data - withoutHeader-ID or length specifier.
      abstract void parseFromCentralDirectoryData(Array<byte> buffer, int offset, int length) Populate data from this array as if it was in central directory data.
      abstract void parseFromLocalFileData(Array<byte> buffer, int offset, int length) Populate data from this array as if it was in local file data.
