Collection

Where a list of "items" have to be returned a Brotkrueml\FeedGenerator\Collection\Collection object comes into the game:

  • List of authors of a feed or an item (Collection<AuthorInterface>)
  • List of attachments of an item (Collection<AttachmentInterface>)
  • List of categories of a feed (Collection<CategoryInterface>)
  • List of items of a feed (Collection<ItemInterface>)

A collection can be used like this:

// use Brotkrueml\\FeedGenerator\\Collection\\Collection
// use Brotkrueml\\FeedGenerator\\Contract\\AuthorInterface

/**
 * @var Collection<AuthorInterface> $authorCollection
 */
$authorCollection = new Collection();
$authorCollection->add($author1);
// Also multiple authors can be added at once
$authorCollection->add($author2, $author3);

// ... same for the other items ...
