Field Detail

strats

private LongStrategyType[] strats
The indefinite iterators being concatenated.

Specifications: spec_public non_null
is in groups: objectState
maps strats[*].objectState \into objectState
Constructor Detail

LongCompositeStrategy

public LongCompositeStrategy(non_null LongStrategyType s)
Initialize this composite to return the iterator given by the given argument strategy.

Specifications:
assignable strats;

LongCompositeStrategy

public LongCompositeStrategy(non_null LongStrategyType s1,
                             non_null LongStrategyType s2)
Initialize this composite to return the iterator given by the given argument strategies, in order.

Specifications:
assignable strats;

LongCompositeStrategy

public LongCompositeStrategy(non_null LongStrategyType[] strats)
Initialize this composite to return the iterator given by the given argument strategies, in order.

Specifications:
requires \nonnullelements(strats);
assignable this.strats;
ensures java.util.Arrays.equals(this.strats,strats);
Method Detail

longIterator

public LongIterator longIterator()
Description copied from interface: LongStrategyType
Compute a fresh LongIterator, which can be used to provide test data of type long. The LongIterator 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 inherited from overridden method in interface LongStrategyType:
assignable objectState;
ensures \fresh(\result );
ensures_redundantly \result != null;
