Checkstyle for subclass of BaseEvents

Question

I am using checkstyle plugin for Java. However I want to design a checkstyle that: subclass of BaseEvents should only have class variables as final.

Answer 1

Please read over http://checkstyle.sourceforge.net/writingchecks.html .

Your check will have to examine the class for an extends of BaseEvents. You will have to make sure the correct the BaseEvents is given in the imports. ONce you have identified that the class meets your requirements, validate all fields to have the final modifier.

I recommend using http://checkstyle.sourceforge.net/writingchecks.html#Tool_to_print_Java_tree_structure to print the tree structure of your java files and how to navigate the tree and where to find things.
