IntCompositeStrategy

public IntCompositeStrategy(non_null IntStrategyType[] strats)

Initialize this composite to return the iterator given by the given argument strategies, in order.

Specifications:

requires \nonnullelements(strats);

intIterator

public IntIterator intIterator()

Description copied from interface: IntStrategyType

Compute a fresh IntIterator, which can be used to provide test data of type int. The IntIterator 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 IntStrategyType:

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