          public Archives()

  - ### Method Detail

    - #### createZips

          public Union createZips()

      Wrapper to identify nested resource collections as ZIP archives.

    - #### createTars

          public Union createTars()

      Wrapper to identify nested resource collections as ZIP archives.

    - #### size

          public int size()

      Sums the sizes of nested archives.
      Specified by:
        `size` in interface `ResourceCollection`
      Returns:
        number of elements as int.

    - #### iterator

          public java.util.Iterator<Resource> iterator()

      Merges the nested collections.
      Specified by:
        `iterator` in interface `java.lang.Iterable<Resource>`
      Specified by:
        `iterator` in interface `ResourceCollection`
      Returns:
        all resources in the collection

    - #### isFilesystemOnly

          public boolean isFilesystemOnly()

      Description copied from interface: `ResourceCollection`
      Indicate whether this ResourceCollection is composed entirely of Resources accessible via local filesystem conventions. If true, all resources returned from this collection should respond with a `FileProvider` when asked via `Resource.as(java.lang.Class<T>)`.
      Specified by:
        `isFilesystemOnly` in interface `ResourceCollection`
      Returns:
        false

    - #### setRefid

      Overrides:
        `setRefid` in class `DataType`
      Parameters:
        `r` - the Reference to set.

    - #### clone

          public java.lang.Object clone()

      Implement clone. The nested resource collections are cloned as well.
      Overrides:
        `clone` in class `DataType`
      Returns:
        a cloned instance.

    - #### grabArchives

          protected java.util.Iterator<ArchiveFileSet> grabArchives()

      Turns all nested resources into corresponding ArchiveFileSets and returns an iterator over the collected archives.

    - #### configureArchive

          protected ArchiveFileSet configureArchive(ArchiveFileSet afs,
                                                    Resource src)

      Configures the archivefileset based on this type's settings, set the source.
