ByteCompositeStrategy

public ByteCompositeStrategy(non_null ByteStrategyType[] strats)

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

Specifications:

byteIterator

public ByteIterator byteIterator()

Description copied from interface: ByteStrategyType

Compute a fresh ByteIterator, which can be used to provide test data of type byte. The ByteIterator 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 ByteStrategyType:

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