generateRequest

public BatchGetItemRequest 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<BatchGetItemRequest,BatchGetItemIterable,Iterable<BatchGetItem.ResultsPage>>

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 Iterable<BatchGetItem.ResultsPage> transformResponse(BatchGetItemIterable 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<BatchGetItemRequest,BatchGetItemIterable,Iterable<BatchGetItem.ResultsPage>>

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.

getServiceCall

public Function<BatchGetItemRequest,BatchGetItemIterable> getServiceCall(DynamoDbClient dynamoDbClient)

Description copied from interface: DatabaseOperation

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

Specified by:

getServiceCall in interface DatabaseOperation<BatchGetItemRequest,BatchGetItemIterable,Iterable<BatchGetItem.ResultsPage>>

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.
