@Override
public R getResult() {
Reduce<Object, R, R> aggregator = new Reduce<Object, R, R>() {
@Override
public R apply(R soFar, Object key, R item) {
if (soFar != null) {
throw new IllegalStateException("scope contains multiple renderings");
} else {
return item;
}
}
};
// Thread aggregator through the rendering maps, ensuring there is at most
// one rendering in any of them.

return rendering;
