类名称：CollectionUtils
方法名：predicatedCollection

CollectionUtils.predicatedCollection介绍

[英]Returns a predicated (validating) collection backed by the given collection.

Only objects that pass the test in the given predicate can be added to the collection. Trying to add an invalid object results in an IllegalArgumentException. It is important not to use the original collection after invoking this method, as it is a backdoor for adding invalid objects.
[中]返回给定集合支持的谓词（验证）集合。
只有在给定谓词中通过测试的对象才能添加到集合中。尝试添加无效对象会导致IllegalArgumentException。调用此方法后不要使用原始集合，因为它是添加无效对象的后门。

public void testPredicatedCollection() {
  Predicate predicate = new Predicate() {
    public boolean evaluate(Object o) {
      return o instanceof String;
    }
  };
  Collection collection = 
    CollectionUtils.predicatedCollection(new ArrayList(), predicate);
  assertTrue("returned object should be a PredicatedCollection",
    collection instanceof PredicatedCollection);
  try { 
    collection = 
      CollectionUtils.predicatedCollection(new ArrayList(), null); 
    fail("Expecting IllegalArgumentException for null predicate.");
  } catch (IllegalArgumentException ex) {
    // expected
  }
  try { 
    collection = 
      CollectionUtils.predicatedCollection(null, predicate); 
    fail("Expecting IllegalArgumentException for null collection.");
  } catch (IllegalArgumentException ex) {
    // expected
  }             
}
