Method Detail

samples

public SampleElements<Map.Entry<K,V>> samples()

Description copied from interface: TestContainerGenerator

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

Specified by:

samples in interface TestContainerGenerator<K,V>

create

public Set<Map.Entry<K,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<K,V>

Specified by:

create in interface TestSetGenerator<K>

createFromEntries

public abstract Set<Map.Entry<K,V>> createFromEntries(Map.Entry<K,V>[] entries)

createArray

public Map.Entry<K,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<K,V>

order

public List<Map.Entry<K,V>> order(List<Map.Entry<K,V>> insertionOrder)

Returns the original element list, unchanged.

Specified by:

order in interface TestContainerGenerator<K,V>
