### Constructor Detail

#### Archives

    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

    public void setRefid(Reference r)

Overrides the base version.

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.

#### dieOnCircularReference

    protected void dieOnCircularReference(java.util.Stack<java.lang.Object> stk,
                              Project p)
                                   throws BuildException

Overrides the version of DataType to recurse on all DataType child elements that may have been added.

Overrides:
  `dieOnCircularReference` in class `DataType`
Parameters:
  `stk` - the stack of data types to use (recursively).
  `p` - the project to use to dereference the references.
Throws:
  `BuildException` - on error.
