列出所有具有完全限定名称的子类

问题描述

我想获得一个给定类的所有子类的列表，其全部限定名称。我想将它从Eclipse中复制并粘贴到这样的文本文件中：

I would like to get a list of all subclasses of a given class with their fully qualified names. I wanted to copy it from Eclipse and paste into a text file like this:

 some.package.Class1
 some.package.Class2
 some.other.package.Class3
 ...

我试过：

• 做搜索| Java |类型，对实现者的限制。 但是由于一些奇怪的原因，这个没有列出子类的子类，只是直接后代。


• 开始层次结构查看打印树组件中所有子类的类，但此视图不允许我选择所有行并复制其名称。

• doing Search | Java | Type, Limit to implementors. But this one for some strange reasons doesn't list subclasses of subclasses, only direct descendants.
• opening Hierarchy view for the class which prints all the subclasses in a tree component, but this view doesn't allow me to select all the rows and copy their names.

其他任何技巧？有数百个类，所以我想避免手动执行。

Any other tricks? There are hundreds of classes, so I wanted to avoid doing it manually.

推荐答案

按照可以以编程方式执行。这是一个耻辱的Eclipse不能做它的OOTB。在Java代码中执行此操作可以无需额外的费用进行过滤（例如！（klazz.isEnum（）））。

Following the pattern described in http://internna.blogspot.com/2007/11/java-5-retrieving-all-classes-from.html one can do it programmatically. It's a shame Eclipse can't do it OOTB. Doing it in Java code allows to do the filtering with no additional cost (e.g. !(klazz.isEnum())).
