Method Details

samples

public SampleElements<Map.Entry<AnEnum,String>> samples()

Description copied from interface: TestContainerGenerator

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

Specified by:

samples in interface TestContainerGenerator<Map<AnEnum,String>, Map.Entry<AnEnum,String>>

create

public final Map<AnEnum,String> create(Object... entries)

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<Map<AnEnum,String>, Map.Entry<AnEnum,String>>

create

protected abstract Map<AnEnum,String> create(Map.Entry<AnEnum,String>[] entries)

createArray

public final Map.Entry<AnEnum,String>[] 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<Map<AnEnum,String>, Map.Entry<AnEnum,String>>

createKeyArray

public final AnEnum[] createKeyArray(int length)

Specified by:

createKeyArray in interface TestMapGenerator<AnEnum,String>

createValueArray

public final String[] createValueArray(int length)

Specified by:

createValueArray in interface TestMapGenerator<AnEnum,String>

order

public Iterable<Map.Entry<AnEnum,String>> order(List<Map.Entry<AnEnum,String>> insertionOrder)

Returns the elements sorted in natural order.

Specified by:

order in interface TestContainerGenerator<Map<AnEnum,String>, Map.Entry<AnEnum,String>>
