本文整理了Java中org.apache.felix.ipojo.metadata.Element.getElements()方法的一些代码示例，展示了Element.getElements()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Element.getElements()方法的具体详情如下：
包路径：org.apache.felix.ipojo.metadata.Element
类名称：Element
方法名：getElements

Element.getElements介绍

[英]Gets sub-elements. If no sub-elements, an empty array is returned.
[中]获取子元素。如果没有子元素，则返回空数组。
