@GwtCompatible
public interface TestContainerGenerator<T,E>
To be implemented by test generators of things that can contain
elements. Such things include both Collection
and Map
; since
there isn't an established collective noun that encompasses both of these,
'container' is used.
This class is GWT compatible.

Method Summary |
T |
create(Object... elements)
Creates a new container containing the given elements. |
E[] |
createArray(int length)
Helper method to create an array of the appropriate type used by this
generator. |
Iterable<E> |
order(List<E> insertionOrder)
Returns the iteration ordering of elements, given the order in
which they were added to the container. |
SampleElements<E> |
samples()
Returns the sample elements that this generate populates its container
with. |
samples
SampleElements<E> samples()
- Returns the sample elements that this generate populates its container
with.
create
T create(Object... elements)
- Creates a new container containing the given elements. TODO: would be nice
to figure out how to use E... or E[] as a parameter type, but this doesn't
seem to work because Java creates an array of the erased type.
createArray
E[] createArray(int length)
- Helper method to create an array of the appropriate type used by this
generator. The returned array will contain only nulls.
order
Iterable<E> order(List<E> insertionOrder)
- Returns the iteration ordering of elements, given the order in
which they were added to the container. This method may return the
original list unchanged, the original list modified in place, or a
different list.
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.
