e.g.
Copy code
instances(className: "com.squareup.example.Foo") {
  someField
  someOtherField  
}

As GraphQL is strictly typed by definition, it is a bit hard to have dynamic fields like this. But I have seen other GraphQL implementations have support for JSON data type. This could be something that KGraphQL should also have support for.
But you can easily create a base class and then have something like this:
Copy code
type<Foo> {
  property<String>("someField") {
    resolver { "Value to return" }
  }
  property<String>("someOtherField") {
    resolver { "Other value to return" }
  }
}

interesting, I need to think about this. I was basically thinking that the parameters provided would help locate the type and its fields. On the other hand, I might be able to work around that by registering all known classes in the heap dump on start, and do what you just suggested.

I'm not really sure what your "heap dump" is. But if these are some random document data structure, then it will probably be a bit hard getting them into GraphQL types. But most likely those types have some specific class structure and it's just the matter of returning them correctly

A heap dump is a copy of the java heap. Classes, instances, etc.

I'm not sure what structure or how you would get that information into your Kotlin code. But I guess it can be in a String format. So you could create a GraphQL scalar for it using 
stringScalar
and then where ever you use your graphql service, you can deserialize it however you want.

thx, I’ll play again with it when they fix the compose bug 🙂
(but yeah anyway that information presents itself in the form of the API I wrote for the heap dump parser, which is somewhat similar to Java reflection APIs)
