T |
create(Object... elements)
Creates a new container containing the given elements. |

createArray(int length)
Helper method to create an array of the appropriate type used by this generator. |
Iterable<UnhashableObject> |
order(List<UnhashableObject> insertionOrder)

This method runs only when CollectionFeature.KNOWN_ORDER
is specified when creating the test suite. It should never run when testing
containers such as HashSet
, which have a
non-deterministic iteration order.
