Modifier and Type	Method and Description
Function<UpdateItemRequest,CompletableFuture<UpdateItemResponse>>	asyncServiceCall(DynamoDbAsyncClient dynamoDbAsyncClient) Provides a function for making the low level non-blocking asynchronous SDK call to DynamoDb.
static <T> UpdateItemOperation<T>	create(UpdateItemEnhancedRequest<T> request)
UpdateItemRequest	generateRequest(TableSchema<T> tableSchema, OperationContext operationContext, DynamoDbEnhancedClientExtension extension) This method generates the request that needs to be sent to a low level DynamoDbClient.
TransactWriteItem	generateTransactWriteItem(TableSchema<T> tableSchema, OperationContext operationContext, DynamoDbEnhancedClientExtension dynamoDbEnhancedClientExtension)
Function<UpdateItemRequest,UpdateItemResponse>	serviceCall(DynamoDbClient dynamoDbClient) Provides a function for making the low level synchronous SDK call to DynamoDb.
T	transformResponse(UpdateItemResponse response, TableSchema<T> tableSchema, OperationContext operationContext, DynamoDbEnhancedClientExtension extension) 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 <T> UpdateItemOperation<T> create(UpdateItemEnhancedRequest<T> request)

generateRequest

public UpdateItemRequest generateRequest(TableSchema<T> tableSchema,
                                         OperationContext operationContext,
                                         DynamoDbEnhancedClientExtension extension)

Description copied from interface: CommonOperation

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

Specified by:

generateRequest in interface CommonOperation<T,UpdateItemRequest,UpdateItemResponse,T>

Parameters:

tableSchema - A TableSchema that maps the table to a modelled object.

operationContext - An object containing the context, or target, of the command execution.

extension - A DynamoDbEnhancedClientExtension 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 T transformResponse(UpdateItemResponse response,
                           TableSchema<T> tableSchema,
                           OperationContext operationContext,
                           DynamoDbEnhancedClientExtension extension)

Description copied from interface: CommonOperation

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 CommonOperation<T,UpdateItemRequest,UpdateItemResponse,T>

Parameters:

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

tableSchema - A TableSchema that maps the table to a modelled object.

operationContext - An object containing the context, or target, of the command execution.

extension - A DynamoDbEnhancedClientExtension 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<UpdateItemRequest,UpdateItemResponse> serviceCall(DynamoDbClient dynamoDbClient)

Description copied from interface: CommonOperation

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

Specified by:

serviceCall in interface CommonOperation<T,UpdateItemRequest,UpdateItemResponse,T>

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<UpdateItemRequest,CompletableFuture<UpdateItemResponse>> asyncServiceCall(DynamoDbAsyncClient dynamoDbAsyncClient)

Description copied from interface: CommonOperation

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

Specified by:

asyncServiceCall in interface CommonOperation<T,UpdateItemRequest,UpdateItemResponse,T>

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.

generateTransactWriteItem

public TransactWriteItem generateTransactWriteItem(TableSchema<T> tableSchema,
                                                   OperationContext operationContext,
                                                   DynamoDbEnhancedClientExtension dynamoDbEnhancedClientExtension)
