Models with extension and implementation

[bhuyanp]

It will be nice to have capability to generate Models with super classes and implementing interfaces. Most common use case is Seriablizable.

public Foo implements java.io.Serializable{

}

Would you expect this to be specific for java.io.Serializable or a more general solution to add any marker interface?

Next question would be if it would be a global setting, i.e. it would add add it to all DTOs, or a "by model" setting (which would need a way to configure it)?

Thanks for responding.

More generic solution would be nice. Also ability to apply them on per api basis would be nice. Here's an example how I am envisioning it. Should be applied to pojos and records.

map:
  model-interfaces:
    - a.b.InterfaceA
  paths:
    /api/test:
      model-interfaces:
        - a.b.InterfaceB
        - a.b.InterfaceC

In this example, pojos under /api/test should implement all three interfaces and others should implement InterfaceA.

just listing the interfaces will not work, because it gives no control over the types that should implement the interface.

I think something like this

map:
  types:
    # the generated model/dto for "Foo" should implement java.io.Serializable
    - type: Foo <= java.io.Serializable
    # let all generated model/dtos implement java.io.Serializable
    - type: object <= java.io.Serializable

would fit better, beeing more similar to the existing configuration.

I'm not satisfied with the <= . It doesn't really trigger the "implements" association.

- type: Foo <- java.io.Serializable
- type: Foo : java.io.Serializable not sure if it gets to confusing, more colons
- type: Foo is java.io.Serializable
- type: Foo implements java.io.Serializable

You are right, this is more in-line with the existing configuration patterns. My vote is for the below.

map:
  types:
   - type: Foo implements java.io.SomethingElse
   - type: object implements java.io.Serializable
