implement expressive toString methods for model objects

[herrwieger]

Currently most of the classes in the models packages have no toString method. For logging its essential to get meaningful output from model objects via toString. Although its boring work, adding toString methods would make debugging way more fun and increase the usefulness of the sdk.

Hi @herrwieger

Thanks for your advice. I will park this until the iteration slows down and I get some time to get back to this. After the same time, if you'd like to contribute or have an urgent need, please feel free to make your changes in our template for all models: https://github.com/Azure/autorest/blob/master/AutoRest/Generators/Java/Java/Templates/ModelTemplate.cshtml. Changes in that template will be propagated to all models in the SDK.

perhaps this will be part of our JSON serialization work, so on the To Do list for now.

@anuchandy just some food for thought perhaps related to the JSon serialization investigation

@anuchandy Any updates on this issue?

Potential autorest v3 item.

Due to the extensive amount of custom serialization we do in the pipeline, there's no simple toString() implementation available. A simple toString() implementation will be confusing as it will differ from what's sent to the service. I would suggest adding in your watch window JacksonAdapter.createDefaultSerializerAdapter().serialize(modelObject).
