Interface TableOperation<ItemT,RequestT,ResponseT,ResultT>

Type Parameters:

ItemT - The modelled object that this table maps records to.

RequestT - The type of the request object for the DynamoDb call in the low level DynamoDbClient.

ResponseT - The type of the response object for the DynamoDb call in the low level DynamoDbClient.

ResultT - The type of the mapped result object that will be returned by the execution of this operation.

All Superinterfaces:

CommonOperation<ItemT,RequestT,ResponseT,ResultT>

All Known Implementing Classes:

CreateTableOperation, DeleteItemOperation, DeleteTableOperation, DescribeTableOperation, GetItemOperation, PutItemOperation, UpdateItemOperation

public interface TableOperation<ItemT,RequestT,ResponseT,ResultT>
extends CommonOperation<ItemT,RequestT,ResponseT,ResultT>

Interface for a single operation that can be executed against a mapped database table. These operations will be executed against the primary index of the table. Conceptually an operation maps 1:1 with an actual DynamoDb call.

A concrete implementation of this interface should also implement IndexOperation with the same types if the operation supports being executed against both the primary index and secondary indices.

Method Summary

Modifier and Type	Method and Description
default ResultT	executeOnPrimaryIndex(TableSchema<ItemT> tableSchema, String tableName, DynamoDbEnhancedClientExtension extension, DynamoDbClient dynamoDbClient) Default implementation of a complete synchronous execution of this operation against the primary index.
default CompletableFuture<ResultT>	executeOnPrimaryIndexAsync(TableSchema<ItemT> tableSchema, String tableName, DynamoDbEnhancedClientExtension extension, DynamoDbAsyncClient dynamoDbAsyncClient) Default implementation of a complete non-blocking asynchronous execution of this operation against the primary index.

Method Detail

executeOnPrimaryIndex

default ResultT executeOnPrimaryIndex(TableSchema<ItemT> tableSchema,
                                      String tableName,
                                      DynamoDbEnhancedClientExtension extension,
                                      DynamoDbClient dynamoDbClient)

Default implementation of a complete synchronous execution of this operation against the primary index. It will construct a context based on the given table name and then call execute() on the CommonOperation interface to perform the operation.

Parameters:

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

tableName - The physical name of the table to execute the operation against.

dynamoDbClient - A DynamoDbClient to make the call against.

extension - A DynamoDbEnhancedClientExtension that may modify the request or 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.

executeOnPrimaryIndexAsync

default CompletableFuture<ResultT> executeOnPrimaryIndexAsync(TableSchema<ItemT> tableSchema,
                                                              String tableName,
                                                              DynamoDbEnhancedClientExtension extension,
                                                              DynamoDbAsyncClient dynamoDbAsyncClient)

Default implementation of a complete non-blocking asynchronous execution of this operation against the primary index. It will construct a context based on the given table name and then call executeAsync() on the CommonOperation interface to perform the operation.

Parameters:

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

tableName - The physical name of the table to execute the operation against.

dynamoDbAsyncClient - A DynamoDbAsyncClient to make the call against.

extension - A DynamoDbEnhancedClientExtension that may modify the request or result of this operation. A null value here will result in no modifications.

Returns:

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