public class CharExtensibleStrategyDecorator
extends CharAbstractStrategy

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


addedData

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

Constructor Detail

CharExtensibleStrategyDecorator

public CharExtensibleStrategyDecorator(CharStrategyType strat)
Method Detail

charIterator

public CharIterator charIterator()
Description copied from interface: CharStrategyType
Compute a fresh CharIterator, which can be used to provide test data of type char. The CharIterator 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 char[] 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.
