Set<String> |
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.

List<String> |
order(List<String> insertionOrder)
Returns the iteration ordering of elements, given the order in which they were added to the container.

samples()
Returns the sample elements that this generate populates its container with.

TestContainerGeneratorCreates 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.

TestContainerGeneratorHelper method to create an array of the appropriate type used by this generator. The returned array will contain only nulls.
createArray in interface TestContainerGenerator<Collection<String>,String>public List<String> order(List<String> 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.
By default, returns the supplied elements in their given order; however, generators for containers with a known order other than insertion order must override this method.
Note: This default implementation is overkill (but valid) for an unordered container. An equally valid implementation for an unordered container is to throw an exception. The chosen implementation, however, has the advantage of working for insertion-ordered containers, as well.
