A #[ComputedField] may be on a method of the entity's repository, which is given the entity first and is called on the repository the entity manager gives, so a custom repository factory is honoured. Its further parameters are the field's arguments.

With batch: true the method is given a Collection of every entity waiting for the field with the same arguments, keyed by the database value of their identifier, and returns their values keyed the same way, so one query computes them all.

• Resolve\ComputedFieldBatchLoader groups entities by exposed class, field and arguments and calls the method once per group, at most 1000 entities a call. A missing value is null; a method returning neither an array nor a Collection is an error of every entity's field.
• Batched fields may be of an entity type and a list; with batchAssociations off each entity is given alone; extract() leaves batched fields out.
• When the metadata is built: the first parameter must accept the entity, or any Collection for a batch; batch is rejected on an entity's method and for a composite or association identifier.
• Doctrine gives an entity its parent's repository only from a mapped superclass, so an exposed subclass lacking a repository field of its exposed parent throws rather than resolving it as null.
• Two computed fields of one name throw, rather than one silently replacing the other.
• Metadata records repository and batch, left out when unset.
