包路径：org.apache.jena.rdf.model.ResIterator
类名称：ResIterator

ResIterator介绍

[英]An iterator which returns RDF Resources.

RDF iterators are standard Java iterators, except that they have an extra method that returns a specifically typed object, in this case RDF Resource, and have a close() method that should be called to free resources if the caller does not complete the iteration.
[中]返回RDF资源的迭代器。
RDF迭代器是标准的Java迭代器，除了它们有一个额外的方法返回一个特定类型的对象，在本例中是RDF资源，还有一个close()方法，如果调用方没有完成迭代，应该调用该方法释放资源。
