It returns data about reactions to posts or comments but doesn't return the comments or posts themselves.
Since Facebook doesn't provide a key for a single reaction, the ID slot for this kind of collection doesn't uniquely identify a reaction on Facebook.

As a consequence, you cannot build a reactions collection starting from atomic IDs, but you must pass an instance of a Facebook Posts Collection or a Facebook Comments Collection built using the construction

FacebookPostsCollection-class will build a collection with
all the likes to the posts of the source collection
FacebookCommentsCollection-class will build a collection with
all the likes to the comments of the source collection
FacebookUsersCollection-class will build a collection with
the posts written on the walls of the users in the source collection.
FacebookPhotosCollection-class will build a collection with
the likes to the photos in the source collection. The author of the photo may grant the
user_photos to the current application to perform this action.
FacebookVideosCollection-class will build a collection with
the likes to the videos in the source collection. The author of the photo may grant the
user_videos to the current application to perform this action.
