包路径：org.jdom2.Element
类名称：Element
方法名：hasAttributes

Element.hasAttributes介绍

[英]Indicate whether this Element has any attributes. Where possible you should call this method before calling getAttributes() because calling getAttributes() will create the necessary Attribute List memory structures, even if there are no Attributes attached to the Element. Calling hasAttributes() first can save memory.
[中]指示此元素是否具有任何属性。在可能的情况下，您应该在调用getAttributes（）之前调用此方法，因为调用getAttributes（）将创建必要的属性列表内存结构，即使元素没有附加属性。首先调用hasAttributes（）可以节省内存。
