DistanceToFieldProjectionValueStep (Hibernate Search 6.1.8.Final)

Type Parameters:

N - The next step if a method other than multi() is called, i.e. the return type of methods defined in FieldProjectionOptionsStep when called directly on this object.

T - The type of projected distances.

All Superinterfaces:

DistanceToFieldProjectionOptionsStep<N,T>, ProjectionFinalStep<T>
```
public interface DistanceToFieldProjectionValueStep<N extends DistanceToFieldProjectionOptionsStep<?,T>,T>
extends DistanceToFieldProjectionOptionsStep<N,T>
```
The initial step in a "distance to field" projection definition, where the projection (optionally) can be marked as multi-valued (returning Lists), and where optional parameters can be set.
By default (if multi() is not called), the projection is considered single-valued, and its creation will fail if the field is multi-valued.

  DistanceToFieldProjectionOptionsStep<?,List<T>> multi()
  Defines the projection as multi-valued, i.e.

```
DistanceToFieldProjectionOptionsStep<?,List<T>> multi()
```
    Defines the projection as multi-valued, i.e. returning List<T> instead of T.
    Calling multi() is mandatory for multi-valued fields, otherwise the projection will throw an exception upon creating the query.
    
    Returns:
    
    A new step to define optional parameters for the multi-valued projections.
