public abstract class ShortExtensibleStrategy
extends ShortAbstractStrategy

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

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.

public ShortExtensibleStrategy()
Method Detail

shortIterator

public ShortIterator shortIterator()
Description copied from interface: ShortStrategyType
Compute a fresh ShortIterator, which can be used to provide test data of type short. The ShortIterator 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).

Specifications inherited from overridden method in interface ShortStrategyType:
assignable objectState;
ensures \fresh(\result );
ensures_redundantly \result != null;

getData

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

Specifications:
protected normal_behavior
assignable objectState;
ensures \result != null;

defaultData

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

Specifications:
protected normal_behavior
assignable objectState;
ensures \result != null;

addData

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

Specifications:
protected normal_behavior
assignable objectState;
ensures \result != null;
