generateRequest
public GetItemRequest generateRequest(TableSchema<T> tableSchema, OperationContext context, DynamoDbEnhancedClientExtension extension) Description copied from interface:CommonOperation
This method generates the request that needs to be sent to a low levelDynamoDbClient
.- Specified by:
generateRequest
in interfaceCommonOperation<T,
GetItemRequest, GetItemResponse, GetItemEnhancedResponse<T>> - Parameters:
tableSchema
- ATableSchema
that maps the table to a modelled object.context
- An object containing the context, or target, of the command execution.extension
- ADynamoDbEnhancedClientExtension
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 GetItemEnhancedResponse<T> transformResponse(GetItemResponse response, TableSchema<T> tableSchema, OperationContext context, 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 interfaceCommonOperation<T,
GetItemRequest, GetItemResponse, GetItemEnhancedResponse<T>> - Parameters:
response
- The response object returned by the DynamoDb call for this operation.tableSchema
- ATableSchema
that maps the table to a modelled object.context
- An object containing the context, or target, of the command execution.extension
- ADynamoDbEnhancedClientExtension
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
Description copied from interface:CommonOperation
Provides a function for making the low level synchronous SDK call to DynamoDb.- Specified by:
serviceCall
in interfaceCommonOperation<T,
