Interface WiringFactory

All Known Implementing Classes:

CombinedWiringFactory, NoopWiringFactory

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
DataFetcher	getDataFetcher(TypeDefinitionRegistry registry, FieldDefinition definition) Returns a DataFetcher given the type definition
TypeResolver	getTypeResolver(TypeDefinitionRegistry registry, InterfaceTypeDefinition interfaceType) Returns a TypeResolver given the type interface
TypeResolver	getTypeResolver(TypeDefinitionRegistry registry, UnionTypeDefinition unionType) Returns a TypeResolver given the type union
boolean	providesDataFetcher(TypeDefinitionRegistry registry, FieldDefinition definition) This is called to ask if this factory can provide a data fetcher for the definition
boolean	providesTypeResolver(TypeDefinitionRegistry registry, InterfaceTypeDefinition interfaceType) This is called to ask if this factory can provide a type resolver for the interface
boolean	providesTypeResolver(TypeDefinitionRegistry registry, UnionTypeDefinition unionType) This is called to ask if this factory can provide a type resolver for the union

Parameters:

registry - the registry of all types

unionType - the definition to be resolved

Returns:

true if the factory can give out a type resolver

getTypeResolver

TypeResolver getTypeResolver(TypeDefinitionRegistry registry,
                             InterfaceTypeDefinition interfaceType)
