DescriptorImpl which is not public static inside the parent class

[tzach....@gmail.com]

Hi,

I could not find the answer so sorry for asking something that might have been answered already but, can I create a class which will function as DescriptorImpl but not reside inside the parent class as public static class?

Thanks,

Tzach

What problem are you trying to solve that leads you to this question?

From my experience (and I understand it's only me), it is hard to maintain multiple static classes over the years and I would like to make it as easy as possible.

For example, in "io.jenkins.plugins.designlibrary.Select.java", there are multiple static classes and the class kind of loses the single responsibility principle.

So my question is it a must that the DescriptorImpl reside in the same class and as static?

Thanks in advance,

Tzach

Yes, this is possible. See

https://github.com/jenkinsci/plot-plugin/blob/7e7504adc1f710a384af9961ea3940ab2ed11657/src/main/java/hudson/plugins/plot/PlotDescriptor.java

What can be seen frequently is that there is an abstract Descriptor implementation for extension points in a separate class, but the actual extensions have the descriptor as static inner class.

I think the reason why the descriptor implementation is usually a static inner class is because there is a tight relation between them. And quite often the descriptor contains few methods.

Big thanks Markus, this really helps me understand the relation between the Descriptor and the class it is describing! 

And also the config.jelly placement :)
