Constructor Summary

MapTestSuiteBuilder.MapValueCollectionGenerator(OneSizeTestContainerGenerator<Map<K,V>,Map.Entry<K,V>> mapGenerator)

Method Summary

Collection<V>	create(Object... elements) Creates a new container containing the given elements.
V[]	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<V>	order(List<V> insertionOrder) Returns the iteration ordering of elements, given the order in which they were added to the container.
SampleElements<V>	samples() Returns the sample elements that this generate populates its container with.

Method Detail

samples

public SampleElements<V> samples()

Description copied from interface: TestContainerGenerator

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

Specified by:

samples in interface TestContainerGenerator<Collection<V>,V>

create

public Collection<V> 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<V>,V>

createArray

public V[] 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<V>,V>

order

public Iterable<V> order(List<V> 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.

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.

Specified by:

order in interface TestContainerGenerator<Collection<V>,V>

getInnerGenerator

public OneSizeTestContainerGenerator<Map<K,V>,Map.Entry<K,V>> getInnerGenerator()

Specified by:

getInnerGenerator in interface DerivedGenerator
