Method Detail

create

public static TransactGetItemsOperation create(TransactGetItemsEnhancedRequest request)

generateRequest

public TransactGetItemsRequest generateRequest(MapperExtension mapperExtension)

Description copied from interface: DatabaseOperation

This method generates the request that needs to be sent to a low level DynamoDbClient.

Specified by:

generateRequest in interface DatabaseOperation<TransactGetItemsRequest,TransactGetItemsResponse,List<TransactGetResultPage>>

Parameters:

mapperExtension - A MapperExtension that may modify the request of this operation. A null value here will result in no modifications.

Returns:

A request that can be used as an argument to a DynamoDbClient call to perform the operation.

serviceCall

public Function<TransactGetItemsRequest,TransactGetItemsResponse> serviceCall(DynamoDbClient dynamoDbClient)

Description copied from interface: DatabaseOperation

Provides a function for making the low level synchronous SDK call to DynamoDb.

Specified by:

serviceCall in interface DatabaseOperation<TransactGetItemsRequest,TransactGetItemsResponse,List<TransactGetResultPage>>

Parameters:

dynamoDbClient - A low level DynamoDbClient to make the call against.

Returns:

A function that calls DynamoDb with a provided request object and returns the response object.

asyncServiceCall

Parameters:

dynamoDbAsyncClient - A low level DynamoDbAsyncClient to make the call against.

Returns:

A function that calls DynamoDb with a provided request object and returns a CompletableFuture for the response object.

public List<TransactGetResultPage> transformResponse(TransactGetItemsResponse response,
                                                     MapperExtension mapperExtension)

Description copied from interface: DatabaseOperation

Takes the response object returned by the actual DynamoDb call and maps it into a higher level abstracted result object.

Specified by:

transformResponse in interface DatabaseOperation<TransactGetItemsRequest,TransactGetItemsResponse,List<TransactGetResultPage>>

Parameters:

response - The response object returned by the DynamoDb call for this operation.

mapperExtension - A MapperExtension that may modify the result of this operation. A null value here will result in no modifications.
