Interface PaginatedIndexOperation<ItemT,RequestT,ResponseT>

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.

All Superinterfaces:

PaginatedOperation<ItemT,RequestT,ResponseT>

All Known Implementing Classes:

QueryOperation, ScanOperation

public interface PaginatedIndexOperation<ItemT,RequestT,ResponseT>
extends PaginatedOperation<ItemT,RequestT,ResponseT>

Interface for an operation that can be executed against a secondary index of a mapped database table and is expected to return a paginated list of results. Typically, each page of results that is served will automatically perform an additional service call to DynamoDb to retrieve the next set of results.

A concrete implementation of this interface should also implement PaginatedTableOperation 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 PageIterable<ItemT>	executeOnSecondaryIndex(TableSchema<ItemT> tableSchema, String tableName, String indexName, DynamoDbEnhancedClientExtension extension, DynamoDbClient dynamoDbClient) Default implementation of a complete synchronous execution of this operation against a secondary index.
default SdkPublisher<Page<ItemT>>	executeOnSecondaryIndexAsync(TableSchema<ItemT> tableSchema, String tableName, String indexName, DynamoDbEnhancedClientExtension extension, DynamoDbAsyncClient dynamoDbAsyncClient) Default implementation of a complete non-blocking asynchronous execution of this operation against a secondary index.

Method Detail

executeOnSecondaryIndex

default PageIterable<ItemT> executeOnSecondaryIndex(TableSchema<ItemT> tableSchema,
                                                    String tableName,
                                                    String indexName,
                                                    DynamoDbEnhancedClientExtension extension,
                                                    DynamoDbClient dynamoDbClient)

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

Parameters:

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

tableName - The physical name of the table that contains the secondary index to execute the operation against.

indexName - The physical name of the secondary index 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.

executeOnSecondaryIndexAsync

default SdkPublisher<Page<ItemT>> executeOnSecondaryIndexAsync(TableSchema<ItemT> tableSchema,
                                                               String tableName,
                                                               String indexName,
                                                               DynamoDbEnhancedClientExtension extension,
                                                               DynamoDbAsyncClient dynamoDbAsyncClient)

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

Parameters:

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

tableName - The physical name of the table that contains the secondary index to execute the operation against.

indexName - The physical name of the secondary index 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 high level result object as specified by the implementation of this operation.
