Class PaginatedList<T>

java.lang.Object

com.amazonaws.services.dynamodb.datamodeling.PaginatedList<T>

Type Parameters:

T - The domain object type stored in this list.

All Implemented Interfaces:

@Deprecated
public abstract class PaginatedList<T>
extends Object
implements List<T>

Unmodifiable list supporting paginated result sets from Amazon DynamoDB.

Pages of results are fetched lazily from DynamoDB as they are needed. Some methods, such as size() and toArray(), require fetching the entire result set eagerly. See the javadoc of individual methods for details on which are lazy.
