public abstract class LongExtensibleStrategy
extends LongAbstractStrategy

Common code for extensible strategies for providing test data of type long.

This type provides an extension mechanism that is easier to use than a composite, wherein subclasses of subclasses can override the addData() method to provide additional data for testing.

public LongExtensibleStrategy()
Method Detail

longIterator

public LongIterator longIterator()
Description copied from interface: LongStrategyType
Compute a fresh LongIterator, which can be used to provide test data of type long. The LongIterator returned should be freshly created. Usually it should not be at its end. However, in rare cases it might make sense to have an empty iterator be computed (e.g., by filtering).


getData

protected long[] getData()
Create and return the data for the iterations. This is should only be called once for this object.


defaultData

protected abstract long[] defaultData()
Create and return the default data for the iterations. This is should only be called once for this object.


addData

protected long[] addData()
Subclasses can override this to make simple extensions to the data used.
