Field Detail

rawData

private final ShortStrategyType rawData

The test data

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

ShortAbstractFilteringStrategyDecorator

public ShortAbstractFilteringStrategyDecorator(ShortStrategyType strat)

Specifications:

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

shortIterator

public ShortIterator shortIterator()

Description copied from interface: ShortStrategyType

Compute a fresh ShortIterator, which can be used to provide test data of type short. The ShortIterator 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 ShortStrategyType:

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

approve

public abstract boolean approve(short elem)

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