### Question:
StandardGenerator implements Generator { @Override public <A, B> Stream<Meta<A, B>> metaOn(A from, Class<B> to) { return defaultGenerator.metaOn(from, to); } StandardGenerator(
        final DependencyManager dependencyManager,
        final TransformFactory transformFactory
    ); @Override DependencyManager getDependencyMgr(); @Override RenderStack getRenderStack(); @Override Stream<Meta<A, B>> metaOn(A from, Class<B> to); @Override Optional<Meta<A, B>> transform(Transform<A, B> transform, A model,
            TransformFactory factory);  }### Answer:
@Test void metaOn() { assertNotNull(INSTANCE.metaOn(Integer.class, String.class)); }
