Interface DataFetcherFactory<T>

Type Parameters:

T - the type of DataFetcher

@PublicSpi
public interface DataFetcherFactory<T>

A DataFetcherFactory allows a level of indirection in providing DataFetchers for graphql fields. For example if you are using an IoC container such as Spring or Guice, you can use this indirection to give you per request late binding of a data fetcher with its dependencies injected in.
