Using Immutables with AWS DynamoDBMapper

[velpratheesh]

I stumbled across Immutables library and found it to be really good. I am trying to use it with DynamoDBMapper to read/write from Dynamo DB.

DynamoDBMapper only allows mutable objects to be serialized/deserialized. I am running into a issue where DynamoDBMapper writes the value of isInitialized method since it is public. Also throws an exception while reading it since there is no corresponding setter.

Is there a way to generate modifiable classes without isInitialized functionality (or make it private or add DynamoDBIgnore annotation to it)?

Hi @velpratheesh thank you for asking this, sorry for delayed response. I've tried to find a suitable workaround for this and think you can try to rename "isInitialized" method using style annotation, cannot be 100% sure it will work, but here's the example

@Value.Style(
   isInitialized="wasInitialized",  // <-- so it will not recognized as getter by "is*" prefix
   beanFriendlyModifiables=true)   // <-- can improve compatibility with some tools
                                  //making modifiable more like bean (setters return void... etc)

Please, see the introduction to styles: http://immutables.github.io/style.html
