本文整理了Java中org.eclipse.persistence.internal.helper.Helper.getObjectClass()方法的一些代码示例，展示了Helper.getObjectClass()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。Helper.getObjectClass()方法的具体详情如下：
包路径：org.eclipse.persistence.internal.helper.Helper
类名称：Helper
方法名：getObjectClass

Helper.getObjectClass介绍

[英]Returns the object class. If a class is primitive return its non primitive class
[中]返回对象类。如果类是基元类，则返回其非基元类
