REQUIRED. Iterator for this Map state.

@param iteratorBuilder Instance of {@link Iterator.Builder}. Note that
                     the {@link
                     Iterator} object is not built until the {@link MapState} is built so any modifications on the
                     state builder will be reflected in this object.
@return This object for method chaining.
