Direct Known Subclasses:

public class IntExtensibleStrategyDecorator
extends IntAbstractStrategy

A decorator for strategies (which provide test data of type type int) that allows for easy extension to the test data of the underlying strategy.

This type provides an extension mechanism that is easier to use than a composite. To extend the test data, make a subclass that overrides the addData() method; this method provides the additional data for testing.

Field Detail

defaultData

private IntStrategyType defaultData
The default data, returned first in the iterations.


addedData

private IntStrategyType addedData
The added data, returned after the default data in the iterations.

Constructor Detail

IntExtensibleStrategyDecorator

public IntExtensibleStrategyDecorator(IntStrategyType strat)
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).


addData

protected int[] addData()
Subclasses can override this to make simple extensions to the data used. This should only be called once when the object is being constructed.
