public abstract class BooleanExtensibleStrategy
extends BooleanAbstractStrategy

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

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 BooleanExtensibleStrategy()
Method Detail

booleanIterator

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


defaultData

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


addData

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