Method Summary

Methods
Modifier and Type	Method and Description
`Set<K>`	`create(Object... elements)` Creates a new container containing the given elements.
`K[]`	`createArray(int length)` Helper method to create an array of the appropriate type used by this generator.
`OneSizeTestContainerGenerator<Map<K,V>,Map.Entry<K,V>>`	`getInnerGenerator()`
`Iterable<K>`	`order(List<K> insertionOrder)` Returns the iteration ordering of elements, given the order in which they were added to the container.

```
public SampleElements<K> samples()

    Description copied from interface: TestContainerGenerator
    
    Returns the sample elements that this generate populates its container with.

  - create
```
public Set<K> create(Object... elements)
```
    Description copied from interface: TestContainerGenerator
    
    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.
    
    Specified by:
    
    create in interface TestContainerGenerator<Collection<K>,K>
    
    Specified by:
    
    create in interface TestSetGenerator<K>
  - createArray
```
public K[] createArray(int length)
```
    Description copied from interface: TestContainerGenerator
    
    Helper method to create an array of the appropriate type used by this generator. The returned array will contain only nulls.
    
    Specified by:
    
    createArray in interface TestContainerGenerator<Collection<K>,K>
  - order
```
public Iterable<K> order(List<K> insertionOrder)
```
    Description copied from interface: TestContainerGenerator
    
    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.
    If the order is non-deterministic, as with HashSet, this method can return its input unmodified. Provided that the test suite is built without CollectionFeature.KNOWN_ORDER, the tests will look only at the returned contents without regard for order.
    
    Specified by:
    
    order in interface TestContainerGenerator<Collection<K>,K>
