本文整理了Java中com.sun.codemodel.JClass.isAssignableFrom()方法的一些代码示例，展示了JClass.isAssignableFrom()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。JClass.isAssignableFrom()方法的具体详情如下：
包路径：com.sun.codemodel.JClass
类名称：JClass
方法名：isAssignableFrom

JClass.isAssignableFrom介绍

[英]Checks the relationship between two classes.

This method works in the same way as Class#isAssignableFrom(Class)works. For example, baseClass.isAssignableFrom(derivedClass)==true.
[中]检查两个类之间的关系。
此方法的工作方式与类#isAssignableFrom（类）的工作方式相同。例如，基类。isAssignableFrom（derivedClass）=真。
