public abstract class IntExtensibleStrategy
extends IntAbstractStrategy

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

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 IntExtensibleStrategy()
Method Detail

intIterator

public IntIterator intIterator()
Description copied from interface: IntStrategyType
Compute a fresh IntIterator, which can be used to provide test data of type int. The IntIterator 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 int[] getData()
Create and return the data for the iterations. This is should only be called once for this object.


defaultData

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


addData

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