Field Detail

rawData

private final CharStrategyType rawData

The test data

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

CharAbstractFilteringStrategyDecorator

public CharAbstractFilteringStrategyDecorator(CharStrategyType strat)

Specifications:

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

charIterator

public CharIterator charIterator()

Description copied from interface: CharStrategyType

Compute a fresh CharIterator, which can be used to provide test data of type char. The CharIterator 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 CharStrategyType:

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

approve

public abstract boolean approve(char elem)

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