本文整理了Java中org.jdom2.Attribute.getDoubleValue()方法的一些代码示例，展示了Attribute.getDoubleValue()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。Attribute.getDoubleValue()方法的具体详情如下：
包路径：org.jdom2.Attribute
类名称：Attribute
方法名：getDoubleValue

Attribute.getDoubleValue介绍

[英]This gets the value of the attribute, in double form, and if no conversion can occur, throws a DataConversionException
[中]它以double的形式获取属性的值，如果无法进行转换，则抛出DataConversionException
