#object_from_id(type, id, context) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Look up the corresponding object for a provided ID. By default, it uses Relay-style GraphQL::Schema.object_from_id, override this to find objects another way.

Parameters:

  • type (Class, Module) —

    A GraphQL type definition

  • id (String) —

    A client-provided to look up

  • context (GraphQL::Query::Context) —

    the current context
