Field Detail

rawData

private final IntStrategyType rawData
The test data

Specifications: spec_public non_null
is in groups: objectState
maps rawData.objectState \into objectState
Constructor Detail

IntAbstractFilteringStrategyDecorator

public IntAbstractFilteringStrategyDecorator(IntStrategyType strat)
Specifications:
public normal_behavior

assignable rawData;
ensures this.rawData == strat;
Method Detail

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

approve

public abstract boolean approve(int elem)
Return true if the element is to be returned by the getInt() method.

Specifications: pure
public normal_behavior
assignable \nothing;
