    • 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.

      Returns:
      The PipelineConfig.

    • syncConfig

      public final SyncConfig syncConfig()

      The SyncConfig for a resolver attached to a versioned data source.

      Returns:
      The SyncConfig for a resolver attached to a versioned data source.

    • cachingConfig

      public final CachingConfig cachingConfig()

      The caching configuration for the resolver.

      Returns:
      The caching configuration for the resolver.

    • maxBatchSize

      public final Integer maxBatchSize()

      The maximum batching size for a resolver.

      Returns:

      public final AppSyncRuntime runtime()
      Returns the value of the Runtime property for this object.
      Returns:
      The value of the Runtime property for this object.

    • code

      public final String code()

      The resolver code that contains the request and response functions. When code is used, the runtime is required. The runtime value must be APPSYNC_JS.

      Returns:
      The resolver code that contains the request and response functions. When code is used, the runtime is required. The runtime value must be APPSYNC_JS.

    • toBuilder

      public CreateResolverRequest.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<CreateResolverRequest.Builder,CreateResolverRequest>
      Specified by:
      toBuilder in class AppSyncRequest
      Returns:
      a builder for type T

    • builder

      public static CreateResolverRequest.Builder builder()

    • serializableBuilderClass

      public static Class<? extends CreateResolverRequest.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class AwsRequest

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class AwsRequest

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)
      Description copied from class: SdkRequest
      Used to retrieve the value of a field from any class that extends SdkRequest. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, the SdkRequest.getValueForField(String, Class) method will again be available.
      Overrides:
      getValueForField in class SdkRequest
      Parameters:
      fieldName - The name of the member to be retrieved.
      clazz - The class to cast the returned object to.
      Returns:
      Optional containing the casted return value

      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
