    • Method Summary

      Modifier and Type Method Description
      long getNameCRC32()
      void setNameCRC32(long nameCRC32)
      Array<byte> getUnicodeName()
      void setUnicodeName(Array<byte> unicodeName)
      Array<byte> getCentralDirectoryData() The actual data to put into central directory - without Header-ID orlength specifier.
      ZipShort getCentralDirectoryLength() Length of the extra field in the central directory - withoutHeader-ID or length specifier.
      Array<byte> getLocalFileDataData() The actual data to put into local file data - without Header-IDor length specifier.
      ZipShort getLocalFileDataLength() Length of the extra field in the local file data - withoutHeader-ID or length specifier.
      void parseFromCentralDirectoryData(Array<byte> buffer, int offset, int length) Doesn't do anything special since this class always uses thesame data in central directory and local file data.
      void parseFromLocalFileData(Array<byte> buffer, int offset, int length) Populate data from this array as if it was in local file data.
