Method Details

samples

public SampleElements<AnEnum> samples()

Description copied from interface: TestContainerGenerator

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

Specified by:

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

create

public Set<AnEnum> 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<AnEnum>, AnEnum>

Specified by:

create in interface TestSetGenerator<AnEnum>

create

protected abstract Set<AnEnum> create(AnEnum[] elements)

createArray

public AnEnum[] 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<AnEnum>, AnEnum>

order

public List<AnEnum> order(List<AnEnum> insertionOrder)

Sorts the enums according to their natural ordering.

Specified by:

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