public final class Attributes
extends Object
implements Map<String,com.amazonaws.services.dynamodbv2.model.AttributeValue>

DynamoDB item attributes.

It's a convenient immutable builder of a map of attribute values for DynamoDB put operation. Use it like this:

Map<String, AttributeValue> attributes = new Attributes()
   .with("hash", "some value")
   .with("range", 12345);
