DoubleCompositeStrategy

public DoubleCompositeStrategy(non_null DoubleStrategyType[] strats)

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

Specifications:

requires \nonnullelements(strats);

doubleIterator

public DoubleIterator doubleIterator()

Description copied from interface: DoubleStrategyType

Compute a fresh DoubleIterator, which can be used to provide test data of type double. The DoubleIterator 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 DoubleStrategyType:

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