Interface BatchLoaderDelegate<K,V>

All Superinterfaces:

org.dataloader.BatchLoader<K,V>

public interface BatchLoaderDelegate<K,V>
extends org.dataloader.BatchLoader<K,V>

BatchLoaderDelegate is the interface that identifies Spring Beans that help using graphql-java java-dataloader. All the BatchLoaderDelegates are stored in a DataLoaderRegistry. It's actually a map, in which the key is the name for this BatchLoadeDelegate, as returned by getName().
All BatchLoaderDelegates must be defined as Spring Bean, that is: they must be marked by the Component annotation. They are discovered by the GraphQLProvider.dataLoaderRegistry() method.
It is not allowed to have two BatchLoaderDelegates with the same name.
graphql-java-generator will generate one BatchLoaderDelegate implementation for each object defined in the GrapQL schema, which has an ID as a field.
You can register your own BatchDataLoader, by just creating a class which implements BatchLoaderDelegate, and mark it as a Spring Beean with the Component annotation. You just have to check that its name is unique.
