(experimental) Factory class for attribute value assignments.

Example:

 GraphqlApi api = GraphqlApi.Builder.create(this, "Api")
         .name("demo")
         .schema(Schema.fromAsset(join(__dirname, "schema.graphql")))
         .authorizationConfig(AuthorizationConfig.builder()
                 .defaultAuthorization(AuthorizationMode.builder()
                         .authorizationType(AuthorizationType.IAM)
                         .build())
                 .build())
         .xrayEnabled(true)
         .build();
 Table demoTable = Table.Builder.create(this, "DemoTable")
         .partitionKey(Attribute.builder()
                 .name("id")
                 .type(AttributeType.STRING)
                 .build())
         .build();
 DynamoDbDataSource demoDS = api.addDynamoDbDataSource("demoDataSource", demoTable);
 // Resolver for the Query "getDemos" that scans the DynamoDb table and returns the entire list.
 demoDS.createResolver(BaseResolverProps.builder()
         .typeName("Query")
         .fieldName("getDemos")
         .requestMappingTemplate(MappingTemplate.dynamoDbScanTable())
         .responseMappingTemplate(MappingTemplate.dynamoDbResultList())
         .build());
 // Resolver for the Mutation "addDemo" that puts the item into the DynamoDb table.
 demoDS.createResolver(BaseResolverProps.builder()
         .typeName("Mutation")
         .fieldName("addDemo")
         .requestMappingTemplate(MappingTemplate.dynamoDbPutItem(PrimaryKey.partition("id").auto(), Values.projecting("input")))
         .responseMappingTemplate(MappingTemplate.dynamoDbResultItem())
         .build());

Method Detail

attribute

@Stability(value=Experimental)
 @NotNull
public static AttributeValuesStep attribute(@NotNull
                                                                                     String attr)

(experimental) Allows assigning a value to the specified attribute.

Parameters:

attr - This parameter is required.

projecting

@Stability(value=Experimental)
 @NotNull
public static AttributeValues projecting(@Nullable
                                                                                  String arg)

(experimental) Treats the specified object as a map of assignments, where the property names represent attribute names.

It’s opinionated about how it represents some of the nested objects: e.g., it will use lists (“L”) rather than sets (“SS”, “NS”, “BS”). By default it projects the argument container ("$ctx.args").

Parameters:
