All Implemented Interfaces:

BooleanStrategyType, StrategyType

public class BooleanExtensibleStrategyDecorator

extends BooleanAbstractStrategy

A decorator for strategies (which provide test data of type type boolean) 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 BooleanStrategyType defaultData

The default data, returned first in the iterations.

addedData

private BooleanStrategyType addedData

The added data, returned after the default data in the iterations.

BooleanExtensibleStrategyDecorator

public BooleanExtensibleStrategyDecorator(BooleanStrategyType strat)

booleanIterator

public BooleanIterator booleanIterator()

Description copied from interface: BooleanStrategyType

Compute a fresh BooleanIterator, which can be used to provide test data of type boolean. The BooleanIterator 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 boolean[] 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.
