Adds a subselect fetch decriptor for the given entity key.

Clears all entries from this fetch queue.

Clears all pending subselect fetches from the queue.

Get a batch of uninitialized collection keys for a given role

Get a batch of unloaded identifiers for this class, using a slightly complex algorithm that tries to grab keys registered immediately after the given key.

Retrieve the fetch descriptor associated with the given entity key.

After evicting or deleting or loading an entity, we don't need to batch fetch it anymore, remove it from the queue if necessary

After evicting or deleting an entity, we don't need to know the query that was used to load it anymore (don't call this after loading the entity, since we might still need to load its collections)

Constructs a queue for the given context.
