Let's think about a scenario where we need to save a user in the database. I create a method that receives a JSON with the user's information.
At this moment, I receive "name", "email", and "password". Right after that, I create a UserDTO class to map the data.
 

Method createUser(@Request user As test.UserDTO) As%Status {
	// codes...
}

The object that is arriving would be the %request.Content, and when passing it to the createUser method, our @Request is the one that deserializes the JSON into an Iris type.

Example in Java with SpringBoot. 

In this code, Spring Boot has several special variables with their own configurations. Something along those lines.

I’m thinking of creating a new configuration argument, similar to "Output" itself.
