Method Detail


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: non_null
Specifications inherited from overridden method in interface ByteStrategyType:
assignable objectState;
ensures \fresh(\result );
ensures_redundantly \result != null;


public abstract boolean approve(byte elem)
Return true if the element is to be returned by the getByte() method.
