Method Details

exceptionResolvers

B exceptionResolvers(List<DataFetcherExceptionResolver> resolvers)

Add DataFetcherExceptionResolver's that are invoked when a DataFetcher raises an exception. Resolvers are invoked in sequence until one emits a list.

Parameters:

resolvers - the resolvers to add

Returns:

the current builder

subscriptionExceptionResolvers

B subscriptionExceptionResolvers(List<SubscriptionExceptionResolver> resolvers)

Add SubscriptionExceptionResolvers that are invoked when a GraphQL subscription Publisher ends with error, and given a chance to resolve the exception to one or more GraphQL errors to be sent to the client. Resolvers are invoked in sequence until one emits a list.

Parameters:

resolvers - the subscription exception resolver

Returns:

the current builder

Since:

1.0.1

typeVisitors

B typeVisitors(List<GraphQLTypeVisitor> typeVisitors)

Add GraphQLTypeVisitors to visit all element of the created GraphQLSchema and make changes to the GraphQLCodeRegistry.

Note: Visitors are applied via SchemaTraverser and cannot change the schema.

Parameters:

typeVisitors - the type visitors

Returns:

the current builder

See Also:

• SchemaTransformer.transformSchema(GraphQLSchema, GraphQLTypeVisitor)

typeVisitorsToTransformSchema

B typeVisitorsToTransformSchema(List<GraphQLTypeVisitor> typeVisitors)

Alternative to typeVisitors(List) for visitors that also need to make schema changes.

Note: Visitors are applied via SchemaTransformer, and therefore can change the schema. However, this is more expensive than using SchemaTraverser, so generally prefer typeVisitors(List) if it's not necessary to change the schema.

Parameters:

typeVisitors - the type visitors to register

Returns:

the current builder

Since:

1.1.0

See Also:

• SchemaTransformer.transformSchema(GraphQLSchema, GraphQLTypeVisitor)

instrumentation

B instrumentation(List<Instrumentation> instrumentations)

Provide Instrumentation components to instrument the execution of GraphQL queries.

Parameters:

instrumentations - the instrumentation components

Returns:

the current builder

See Also:

• GraphQL.Builder.instrumentation(Instrumentation)

configureGraphQl

B configureGraphQl(Consumer<GraphQL.Builder> configurer)

Configure consumers to be given access to the GraphQL.Builder used to build GraphQL.

Parameters:

configurer - the configurer

Returns:

the current builder

build

GraphQlSource build()

Build the GraphQlSource instance.
