public abstract class CharExtensibleStrategy
extends CharAbstractStrategy

Common code for extensible strategies for providing test data of type char.

This type provides an extension mechanism that is easier to use than a composite, wherein subclasses of subclasses can override the addData() method to provide additional data for testing.

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).


getData

protected char[] getData()
Create and return the data for the iterations. This is should only be called once for this object.


defaultData

protected abstract char[] defaultData()
Create and return the default data for the iterations. This is should only be called once for this object.


addData

protected char[] addData()
Subclasses can override this to make simple extensions to the data used.
