Field Detail

rawData

private final BooleanStrategyType rawData

The test data

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

BooleanAbstractFilteringStrategyDecorator

public BooleanAbstractFilteringStrategyDecorator(BooleanStrategyType strat)

Specifications:

public normal_behavior
requires strat != null;
assignable rawData;
ensures this.rawData == 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).

Specifications: non_null

Specifications inherited from overridden method in interface BooleanStrategyType:

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

approve

public abstract boolean approve(boolean elem)

Return true if the element is to be returned by the getBoolean() method.
