Constructor Details

#initialize(parent_type, field_definition, query, response_path) ⇒ Hash<GraphQL::BaseType, Hash<String, ScopedTypeComplexity>>

Parameters:

  • parent_type (Class) —

    The owner of field_definition

  • field_definition (GraphQL::Field, GraphQL::Schema::Field) —

    Used for getting the .complexity configuration

  • query (GraphQL::Query) —

    Used for query.possible_types

  • response_path (Array<String>) —

    The path to the response key for the field
