Returns:

current collection of MFile as an Iterable.

Throws:

IOException

getFileIterator

public CloseableIterator<MFile> getFileIterator()
                                         throws IOException

Description copied from interface: MCollection

Get the current collection of MFile, no guaranteed order. May be faster than getFilesSorted() for large collections, use when order is not important.

 try (CloseableIterator iter = getFileIterator()) {
   while (iter.hasNext()) {
     MFile file = iter.next();
   }
 }
 

Returns:

current collection of MFile as an CloseableIterator.
