Interface WiringFactory

All Known Implementing Classes:

CombinedWiringFactory, NoopWiringFactory

@PublicSpi
public interface WiringFactory

A WiringFactory allows you to more dynamically wire in TypeResolvers and DataFetchers based on the IDL definitions. For example you could look at the directives say to build a more dynamic set of type resolvers and data fetchers.

Method Summary

Modifier and Type	Method and Description
default DataFetcher	getDataFetcher(FieldWiringEnvironment environment) Returns a DataFetcher given the type definition
default DataFetcher	getDefaultDataFetcher(FieldWiringEnvironment environment) All fields need a data fetcher of some sort and this method is called to provide the data fetcher that will be used if no specific one has been provided
default TypeResolver	getTypeResolver(InterfaceWiringEnvironment environment) Returns a TypeResolver given the type interface
default TypeResolver	getTypeResolver(UnionWiringEnvironment environment) Returns a TypeResolver given the type union
default boolean	providesDataFetcher(FieldWiringEnvironment environment) This is called to ask if this factory can provide a data fetcher for the definition
default boolean	providesTypeResolver(InterfaceWiringEnvironment environment) This is called to ask if this factory can provide a type resolver for the interface
default boolean	providesTypeResolver(UnionWiringEnvironment environment) This is called to ask if this factory can provide a type resolver for the union
