Direct Known Subclasses:

public class ShortExtensibleStrategyDecorator
extends ShortAbstractStrategy

A decorator for strategies (which provide test data of type type short) 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 ShortStrategyType defaultData
The default data, returned first in the iterations.


addedData

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

Constructor Detail

ShortExtensibleStrategyDecorator

public ShortExtensibleStrategyDecorator(ShortStrategyType strat)
Method Detail

shortIterator

public ShortIterator shortIterator()
Description copied from interface: ShortStrategyType
Compute a fresh ShortIterator, which can be used to provide test data of type short. The ShortIterator 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 short[] 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.
