        public final String apiId()

        The ID for the GraphQL API for which the resolver is being created.

        Returns:
        The ID for the GraphQL API for which the resolver is being created.
      • typeName

        public final String typeName()

        The name of the Type.

        Returns:
        The name of the Type.
      • fieldName

        public final String fieldName()

        The name of the field to attach the resolver to.

        Returns:
        The name of the field to attach the resolver to.
      • dataSourceName

        public final String dataSourceName()

        The name of the data source for which the resolver is being created.

        Returns:
        The name of the data source for which the resolver is being created.
      • requestMappingTemplate

        public final String requestMappingTemplate()

        The mapping template to use for requests.

        A resolver uses a request mapping template to convert a GraphQL expression into a format that a data source can understand. Mapping templates are written in Apache Velocity Template Language (VTL).

        VTL request mapping templates are optional when using an Lambda data source. For all other data sources, VTL request and response mapping templates are required.

        Returns:
        The mapping template to use for requests.

      • responseMappingTemplate

        public final String responseMappingTemplate()

        The mapping template to use for responses from the data source.

        Returns:
        The mapping template to use for responses from the data source.
      • kind

        public final ResolverKind kind()

        The resolver type.

        • UNIT: A UNIT resolver type. A UNIT resolver is the default resolver type. You can use a UNIT resolver to run a GraphQL query against a single data source.

        • PIPELINE: A PIPELINE resolver type. You can use a PIPELINE resolver to invoke a series of Function objects in a serial manner. You can use a pipeline resolver to run a GraphQL query against multiple data sources.

        If the service returns an enum value that is not available in the current SDK version, kind will return ResolverKind.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from kindAsString().

        Returns:
        The resolver type.
