CharCompositeStrategy

public CharCompositeStrategy(non_null CharStrategyType[] strats)

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

Specifications:

requires \nonnullelements(strats);

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 inherited from overridden method in interface CharStrategyType:

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