Direct Known Subclasses:

public class FloatExtensibleStrategyDecorator
extends FloatAbstractStrategy

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


addedData

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

Constructor Detail

FloatExtensibleStrategyDecorator

public FloatExtensibleStrategyDecorator(FloatStrategyType strat)
Method Detail

floatIterator

public FloatIterator floatIterator()
Description copied from interface: FloatStrategyType
Compute a fresh FloatIterator, which can be used to provide test data of type float. The FloatIterator 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 float[] 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.
