包路径：org.nakedobjects.metamodel.spec.NakedObjectSpecification
类名称：NakedObjectSpecification
方法名：isCollection

NakedObjectSpecification.isCollection介绍

[英]Determines if objects represents a collection.

In effect, means has got CollectionFacet, and therefore will return NOT #isObject().
[中]确定对象是否表示集合。
实际上，means已经获得了CollectionFacet，因此不会返回#isObject（）。
