Package graphql

Class GraphqlErrorBuilder<B extends GraphqlErrorBuilder<B>>

java.lang.Object

graphql.GraphqlErrorBuilder<B>

Type Parameters:

B - this base class allows you to derive new classes from this base error builder

All Implemented Interfaces:

GraphQLError.Builder<B>

@PublicApi
public class GraphqlErrorBuilder<B extends GraphqlErrorBuilder<B>>
extends java.lang.Object
implements GraphQLError.Builder<B>

This helps you build GraphQLErrors and also has a quick way to make a DataFetcherResults from that error.
