Interface ZipExtraField

  • All Known Implementing Classes:
    AsiExtraField, UnrecognizedExtraField

    public interface ZipExtraField
    This is a class that has been made significantly smaller (deleted a bunch of methods) and originally is from the Apache Ant Project (http://ant.apache.org), org.apache.tools.zip package. All license and other documentation is intact. 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.

        1.1
      • getLocalFileDataLength

        ZipShort getLocalFileDataLength()
        Length of the extra field in the local file data - without Header-ID or length specifier.
        Returns:
        the length of the field in the local file data

        1.1
      • getLocalFileDataData

        byte[] getLocalFileDataData()
        The actual data to put into local file data - without Header-ID or length specifier.
        Returns:
        the data
        Since:
