Question

For classes ending with “**Setup”, the default format rule of ClassName should be replaced with a rule allowing inner class names to start with a lowercase letter – if it extends another class.
How can I do this?

A concrete example:

class MyExampleSetup {

  // valid, turn off ClassName check
  static class myInnerClass extends MyInnerClass() {....}
  // valid, normal class name Check
  static class MyOtherInnerClass () {....}
}

Unfortunately, that is impossible out of the box. What you are really asking for is a modification of behavior for one check (TypeName). The only way of implementing such a thing is by implementing your own custom check.

_{(Like the previous posters, I must urge you to consider using annotations for the background magic instead of relying on the naming convention. But that wasn’t your question of course.)}
