Method Summary

Modifier and Type	Method and Description
Function<BatchGetItemRequest,SdkPublisher<BatchGetItemResponse>>	asyncServiceCall(DynamoDbAsyncClient dynamoDbAsyncClient) Provides a function for making the low level non-blocking asynchronous paginated SDK call to DynamoDb.
static BatchGetItemOperation	create(BatchGetItemEnhancedRequest request)
BatchGetItemRequest	generateRequest(MapperExtension mapperExtension) This method generates the request that needs to be sent to a low level DynamoDbClient.
Function<BatchGetItemRequest,SdkIterable<BatchGetItemResponse>>	serviceCall(DynamoDbClient dynamoDbClient) Provides a function for making the low level synchronous paginated SDK call to DynamoDb.
BatchGetResultPage	transformResponse(BatchGetItemResponse response, MapperExtension mapperExtension) Takes the response object returned by the actual DynamoDb call and maps it into a higher level abstracted result object.

Method Detail

create

public static BatchGetItemOperation create(BatchGetItemEnhancedRequest request)

generateRequest

public BatchGetItemRequest generateRequest(MapperExtension mapperExtension)

Description copied from interface: PaginatedDatabaseOperation

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

Specified by:

generateRequest in interface PaginatedDatabaseOperation<BatchGetItemRequest,BatchGetItemResponse,BatchGetResultPage>

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.

transformResponse

public BatchGetResultPage transformResponse(BatchGetItemResponse response,
                                            MapperExtension mapperExtension)

Description copied from interface: PaginatedDatabaseOperation

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 PaginatedDatabaseOperation<BatchGetItemRequest,BatchGetItemResponse,BatchGetResultPage>

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.

Returns:

A high level result object as specified by the implementation of this operation.

serviceCall

public Function<BatchGetItemRequest,SdkIterable<BatchGetItemResponse>> serviceCall(DynamoDbClient dynamoDbClient)

Description copied from interface: PaginatedDatabaseOperation

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

Specified by:

serviceCall in interface PaginatedDatabaseOperation<BatchGetItemRequest,BatchGetItemResponse,BatchGetResultPage>

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

public Function<BatchGetItemRequest,SdkPublisher<BatchGetItemResponse>> asyncServiceCall(DynamoDbAsyncClient dynamoDbAsyncClient)

Description copied from interface: PaginatedDatabaseOperation

Provides a function for making the low level non-blocking asynchronous paginated SDK call to DynamoDb.

Specified by:

asyncServiceCall in interface PaginatedDatabaseOperation<BatchGetItemRequest,BatchGetItemResponse,BatchGetResultPage>

Parameters:

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

Returns:

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