Field Detail

rawData

private final FloatStrategyType rawData

The test data

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

FloatAbstractFilteringStrategyDecorator

public FloatAbstractFilteringStrategyDecorator(FloatStrategyType strat)

Specifications:

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

floatIterator

public FloatIterator floatIterator()

Description copied from interface: FloatStrategyType

Compute a fresh FloatIterator, which can be used to provide test data of type float. The FloatIterator 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 FloatStrategyType:

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

approve

public abstract boolean approve(float elem)

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