public abstract class DoubleExtensibleStrategy
extends DoubleAbstractStrategy

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

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 DoubleExtensibleStrategy()
Method Detail

doubleIterator

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


defaultData

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


addData

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