Information about directives at application start up

[VitalijF]

I've custom directive which has been defined in schema and also been applied for some input fields

directive @length(max: Int!) on INPUT_FIELD_DEFINITION

After code been generated I've not seen any places where this directive present. So question: is it possible to retrieve information about directive and where it's been applied on start up phase

Hi @VitalijF! Can you please provide some more information about what you are trying to achieve?

There is now way of retrieving info about a directive at startup. With the limited info you provided, you can possibly leverage custom instrumentation classes which give you hooks to inspect and hook into various stages of query processing.

Hello.
So, I've created custom directive
directive @length(max: Int!) on INPUT_FIELD_DEFINITION
and applied it

input TestInput {
    fieldA: String! @length(max: 30)
    fieldB: String! @length(max: 40)
}

The main goal which I try to achieve is to load all these directive values at application start up or at least on fetcher level for applying validation on java side.
