# frozen_string_literal: true module GraphQL # An Interface contains a collection of types which implement some of the same fields. # # Interfaces can have fields, defined with `field`, just like an object type. # # Objects which implement this field _inherit_ field definitions from the interface. # An object type can override the inherited definition by redefining that field. # # @example An interface with three fields # DeviceInterface = GraphQL::InterfaceType.define do # name("Device") # description("Hardware devices for computing") # # field :ram, types.String # field :processor, ProcessorType # field :release_year, types.Int # end # # @example Implementing an interface with an object type # Laptoptype = GraphQL::ObjectType.define do # interfaces [DeviceInterface] # end # class InterfaceType < GraphQL::BaseType accepts_definitions :fields, field: GraphQL::Define::AssignObjectField attr_accessor :fields ensure_defined :fields def initialize @fields = {} end def initialize_copy(other) super @fields = other.fields.dup end def kind GraphQL::TypeKinds::INTERFACE end # @return [GraphQL::Field] The defined field for `field_name` def get_field(field_name) fields[field_name] end # @return [Array<GraphQL::Field>] All fields on this type def all_fields fields.values end end end
