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

DynamoDB query conditions.

It's a convenient immutable builder of a map of conditions for DynamoDB query/scan operations. Use it like this:

Map<String, Condition> conditions = new Conditions()
   .with("hash", Conditions.equalTo("some value"))
   .with("range", Conditions.equalTo(12345));
