Class IntExtensibleStrategy

java.lang.Object
  org.jmlspecs.jmlunit.strategies.IntAbstractStrategy
      org.jmlspecs.jmlunit.strategies.IntExtensibleStrategy

All Implemented Interfaces:

IntStrategyType, StrategyType

Direct Known Subclasses:

IntExtensibleStrategyDecorator.IntExtensibleStrategyDecorator$1, IntStrategy

public abstract class IntExtensibleStrategy

extends IntAbstractStrategy

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

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.

private int[] data

The data to return in the iterations

Specifications: nullable
is in groups: objectState

IntExtensibleStrategy

public IntExtensibleStrategy()

intIterator

public IntIterator intIterator()

Description copied from interface: IntStrategyType

Compute a fresh IntIterator, which can be used to provide test data of type int. The IntIterator 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 IntStrategyType:

assignable objectState;
ensures \fresh(\result );
ensures_redundantly \result != null;

getData

protected int[] 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 int[] 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 int[] addData()

Subclasses can override this to make simple extensions to the data used.
