Class PaginatedScanList<T>
java.lang.Object
com.amazonaws.services.dynamodbv2.datamodeling.PaginatedList<T>
com.amazonaws.services.dynamodbv2.datamodeling.PaginatedScanList<T>
- Type Parameters:
T
- The type of objects held in this list.
- All Implemented Interfaces:
Iterable<T>
,Collection<T>
,List<T>
Implementation of the List interface that represents the results from a scan
in AWS DynamoDB. Paginated results are loaded on demand when the user
executes an operation that requires them. Some operations, such as size(),
must fetch the entire list, but results are lazily fetched page by page when
possible.
This is an unmodifiable list, so callers should not invoke any operations that modify this list, otherwise they will throw an UnsupportedOperationException.
