AbstractRecordCollection implements RecordCollectionInterface, PersistableCollectionInterface, SortableCollectionInterface

AbstractYes

Abstract implementation of a RecordCollection

RecordCollection is a collections of TCA-Records. The collection is meant to be stored in TCA-table sys_file_collections and is manageable via FormEngine.

A RecordCollection might be used to group a set of records (e.g. news, images, contentElements) for output in frontend

The AbstractRecordCollection uses SplDoublyLinkedList for internal storage
