OptionalReferrers

class OptionalReferrers<ParentID : Any, in Parent : Entity<ParentID>, ChildID : Any, out Child : Entity<ChildID>, REF>(reference: Column<REF?>, factory: EntityClass<ChildID, Child>, cache: Boolean, references: Map<Column<*>, Column<*>>? = null) : Referrers<ParentID, Parent, ChildID, Child, REF?>

Deprecated

The OptionalReferrers class is a complete duplicate of the Referrers class; therefore, the latter should be used instead.

Replace with
