BooleanUnmarshaller (AWS SDK for Java 1.11.3 API)

java.lang.Object
- com.amazonaws.services.dynamodbv2.datamodeling.unmarshallers.BooleanUnmarshaller

All Implemented Interfaces:

ArgumentUnmarshaller
```
public class BooleanUnmarshaller
extends Object
implements ArgumentUnmarshaller
```
An unmarshaller that unmarshals DynamoDB Bools (or Numbers) into Java Booleans. Numbers are handled for backwards compatibility with versions of the mapper written before the DynamoDB native Boolean type was added, which stored Java Booleans as either the Number 0 (false) or 1 (true).
