我是Java 8 Streams的新手,并希望将以下代码块转换为Java 8的Stream方式来做同样的事情.

编辑:更新类名称以减少混淆.(删除了Foo,Bar,Baz ...)

ArrayList<PriceList> priceLists = new ArrayList<PriceList>();

// I'm casting to a type-safe List from getObjects() 
// -which is a function I dont have access to. Is there a nice 
// solution to embed this in the stream-syntax?
List<PriceListGroup> distObjects = (List<PriceListGroup>) objects.get(1).getObjects();

for(PriceListGroup group : distObjects) {
    Set<Affiliate> affiliates = group.getAffiliates();
    for(Affiliate affiliate : affiliates) {
        priceLists.add(affiliate.getPriceList());
    }
}
