org.apache.commons.compress.archivers.ArchiveOutputStream
Archive output stream implementations are expected to override the {@link #write(byte[],int,int)} method to improve performance.They should also override {@link #close()} to ensure that any necessarytrailers are added.
The normal sequence of calls when working with ArchiveOutputStreams is:
- Create ArchiveOutputStream object,
- optionally write SFX header (Zip only),
- repeat as needed:
  - {@link #putArchiveEntry(ArchiveEntry)} (writes entry header),
  - {@link #write(byte[])} (writes entry data, as often as needed),
  - {@link #closeArchiveEntry()} (closes entry),
- {@link #finish()} (ends the addition of entries),
- optionally write additional data, provided format supports it,
- {@link #close()}.
Example usage:
