  /**
   * Reimplementation of {@link java.util.zip.ZipOutputStream java.util.zip.ZipOutputStream} to handle the extended functionality of this package, especially
   * internal/external file attributes and extra fields with different layouts for local file data and central directory entries.
   * <p>
   * This class will try to use {@link java.nio.channels.SeekableByteChannel} when it knows that the output is going to go to a file and no split archive shall be
   * created.
   * </p>
   * <p>
   * If SeekableByteChannel cannot be used, this implementation will use a Data Descriptor to store size and CRC information for {@link #DEFLATED DEFLATED}
   * entries, you don't need to calculate them yourself. Unfortunately, this is not possible for the {@link #STORED STORED} method, where setting the CRC and
   * uncompressed size information is required before {@link #putArchiveEntry(ZipArchiveEntry)} can be called.
   * </p>
   * <p>
   * As of Apache Commons Compress 1.3, the class transparently supports Zip64 extensions and thus individual entries and archives larger than 4 GB or with more
   * than 65,536 entries in most cases but explicit control is provided via {@link #setUseZip64}. If the stream can not use SeekableByteChannel and you try to
   * write a ZipArchiveEntry of unknown size, then Zip64 extensions will be disabled by default.
