21/**
22* A generator that relies on a preexisting generator for most of its work. For example, a derived
23* iterator generator may delegate the work of creating the underlying collection to an inner
24* collection generator.
25*
26* <p>{@code GwtTestSuiteGenerator} expects every {@code DerivedIterator} implementation to provide
27* a one-arg constructor accepting its inner generator as an argument. This requirement enables it
28* to generate source code (since GWT cannot use reflection to generate the suites).
