Data annotation overrides toString from parent class [message #1850542]

When annotating a class with @Data, the documentation says that the `toString` method will only be generated if it does not yet exist. However, when extending another class that already overrides `toString`, it is still overridden. I would like to keep the behaviour of the parent class. Is there a way to do this?

E.g.,

class Parent {
  override String toString() {
    "My custom toString"
  }
}

@Data
class Child extends Parent {
  val String name
  // I want to keep the behaviour of Parent::toString
}

i assume you need to check the code of the processor and write your own

Okay thanks, I'll take a look at the source of `Data` then.

If it's a one off, what about creating a toString() method in the child class and call the parent one? This way the @Data annotation will not generate a new one.
