final class LoneElementCollectionWrapper[E, CTC[_]](collection: CTC[E], collecting: Collecting[E, CTC[E]], prettifier: Prettifier, pos: Position)

Wrapper class that adds a loneElement method to any collection type C for which an implicit Collecting[C] is available.

Wrapper class that adds a loneElement method to any collection type C for which an implicit Collecting[C] is available.

Through the implicit conversion provided by trait LoneElement, this class allows you to make statements like:

trav.loneElement should be > 9
Type parameters:
CTC

the "collection type constructor" for the collection on which to add the loneElement method

E

the element type of the collection on which to add the loneElement method

Value parameters:
collecting

a typeclass that enables the loneElement syntax

collection

a collection to wrap in a LoneElementCollectionWrapper, which provides the loneElement method.
