Lambda.collect介绍

[英]Collects the items in the given iterable putting them in a List. Actually it handles also Maps, Arrays and Iterator by collecting their values. Note that this method accepts an Object in order to be used in conjunction with the Lambda#forEach(Iterable).
[中]收集给定iterable中的项并将其放入列表中。实际上，它还通过收集映射、数组和迭代器的值来处理它们。请注意，此方法接受一个对象，以便与Lambda#forEach（Iterable）一起使用。

public List<FormBean> sortByDependency() {

      sortedFormBeans.add(formBean);
      formBeansClone.remove(formBean);
    }
  }
  final List<String> namesOfForms = collect(formBeans, on(FormBean.class).getFormname());
  resolveDependency(sortedFormBeans, formBeansClone, namesOfForms);
  return sortedFormBeans;

/**
 * For each item in the given iterable collects the value defined by the given argument and put them in a List.
 * For example the following code:
 * <pre>
 *         List&lt;Person&gt; myFriends = asList(new Person("Biagio", 39), new Person("Luca", 29), new Person("Celestino", 29));
 *        List&lt;Integer&gt; ages = collect(meAndMyFriends, on(Person.class).getAge());
 * </pre>
 * extracts the ages of all the Persons in the list and put them in a List of Integer.
 * <p/>
 * Actually it handles also Maps, Arrays and Iterator by collecting their values.
 * Note that this method accepts an Object in order to be used in conjunction with the {@link Lambda#forEach(Iterable)}.
 * @param iterable The iterable of which the items should be collected
 * @param argument An argument defined using the {@link Lambda#on(Class)} method 
 * @return A List containing all the items collected from the give iterable
 * @throws RuntimeException if the iterable is not an Iterable or a Map
