Code Example: Initializing GraphQL

public GraphQL graphQL(final String schemaName, final WarbleDataFetcher warbleDataFetcher) {

    final SchemaParser schemaParser = new SchemaParser();
    final SchemaGenerator schemaGenerator = new SchemaGenerator();

    // Parse schema
    final TypeDefinitionRegistry typeRegistry = new TypeDefinitionRegistry();
    
    // SchemaLoader is our component (yet to be implemented) that loads
    // a GraphQL schema as a String
    final String schema = SchemaLoader.by(schemaName);
    
    typeRegistry.merge(schemaParser.parse(schema));

    // New runtime wiring
    final RuntimeWiring runtimeWiring =
            RuntimeWiring.newRuntimeWiring()
                    .type("Query", typeWiring -> typeWiring.dataFetcher("warble", warbleDataFetcher))
                    .build();

    // New executable schema
    final GraphQLSchema graphQLSchema = schemaGenerator.makeExecutableSchema(typeRegistry, runtimeWiring);

    // Answer GraphQL instance
    return GraphQL.newGraphQL(graphQLSchema).build();
}
