- Class
  Description
  ArchiveEntry
  An entry of an archive.
  ArchiveException
  Archiver related Exception.
  ArchiveInputStream<E extends ArchiveEntry>
  Archive input streams MUST override the `FilterInputStream.read(byte[], int, int)` - or `ArchiveInputStream.read()` - method so that reading from the stream generates EOF for the end of data in each entry as well as at the end of the file proper.
  ArchiveOutputStream<E extends ArchiveEntry>
  Archive output stream implementations are expected to override the `OutputStream.write(byte[], int, int)` method to improve performance.
  ArchiveStreamFactory
  Factory to create Archive[In|Out]putStreams from names or the first bytes of the InputStream.
  ArchiveStreamProvider
  Creates Archive `ArchiveInputStream`s and `ArchiveOutputStream`s.
  EntryStreamOffsets
  Provides information about ArchiveEntry stream offsets.
  Lister
  Simple command line application that lists the contents of an archive.
  StreamingNotSupportedException
  Exception thrown by ArchiveStreamFactory if a format is requested/detected that doesn't support streaming.
