Direct Known Subclasses:

public class LongExtensibleStrategyDecorator
extends LongAbstractStrategy

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


addedData

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

Constructor Detail

LongExtensibleStrategyDecorator

public LongExtensibleStrategyDecorator(LongStrategyType strat)
Method Detail

longIterator

public LongIterator longIterator()
Description copied from interface: LongStrategyType
Compute a fresh LongIterator, which can be used to provide test data of type long. The LongIterator 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 long[] 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.
