@Beta
public class UpdateItemExpressionSpec
extends Object

Expression specification for making UpdateItem request to Amazon DynamoDB.

Even though the internal name map and value map are unmodifiable, this object is only as unmodifiable as the underlying values in it's value map. In turn, the values in the value maps are essentially provided by the users of this library. In other words, this object is thread-safe as long as the underlying values provided by the users are thread-safe.
