Class GraphQLCodeRegistry

java.lang.Object

graphql.schema.GraphQLCodeRegistry

@PublicApi
public class GraphQLCodeRegistry
extends java.lang.Object

The GraphQLCodeRegistry holds that execution code that is associated with graphql types, namely the DataFetchers associated with fields, the TypeResolvers associated with abstract types and the GraphqlFieldVisibility

For legacy reasons these code functions can still exist on the original type objects but this will be removed in a future version. Once removed the type system objects will be able have proper hashCode/equals methods and be checked for proper equality.

Method Detail

getFieldVisibility

public GraphqlFieldVisibility getFieldVisibility()

Returns:

the GraphqlFieldVisibility

getDataFetcher

public DataFetcher<?> getDataFetcher(GraphQLFieldsContainer parentType,
                                     GraphQLFieldDefinition fieldDefinition)

Returns a data fetcher associated with a field within a container type

Parameters:

parentType - the container type

fieldDefinition - the field definition

Returns:

the DataFetcher associated with this field. All fields have data fetchers

getDataFetcher

public DataFetcher<?> getDataFetcher(FieldCoordinates coordinates,
                                     GraphQLFieldDefinition fieldDefinition)

Returns a data fetcher associated with a field located at specified coordinates.

Parameters:

coordinates - the field coordinates

fieldDefinition - the field definition

Returns:

the DataFetcher associated with this field. All fields have data fetchers

getTypeResolver

public TypeResolver getTypeResolver(GraphQLInterfaceType interfaceType)

Returns the type resolver associated with this interface type

Parameters:

interfaceType - the interface type

Returns:

a non null TypeResolver

getTypeResolver

public TypeResolver getTypeResolver(GraphQLUnionType unionType)

Returns the type resolver associated with this union type

Parameters:

unionType - the union type

Returns:

a non null TypeResolver

transform

public GraphQLCodeRegistry transform(java.util.function.Consumer<GraphQLCodeRegistry.Builder> builderConsumer)

This helps you transform the current GraphQLCodeRegistry object into another one by starting a builder with all the current values and allows you to transform it how you want.

Parameters:

builderConsumer - the consumer code that will be given a builder to transform

Returns:

a new GraphQLCodeRegistry object based on calling build on that builder

newCodeRegistry

public static GraphQLCodeRegistry.Builder newCodeRegistry()

Returns:

a new builder of GraphQLCodeRegistry objects

newCodeRegistry

public static GraphQLCodeRegistry.Builder newCodeRegistry(GraphQLCodeRegistry existingCodeRegistry)

Returns a new builder of GraphQLCodeRegistry objects based on the existing one

Parameters:

existingCodeRegistry - the existing code registry to use

Returns:

a new builder of GraphQLCodeRegistry objects
