@bamdmux can you show an example?

[bamdmux]

In your case assuming you have

interface Product {
val title: String
val desc: String
}

[bamdmux]

You define

class Clothing(val p: Product, val size: Long): Product by p

[rrader]

this is not really the same, I updated the issue on github
so, class Clothing(@Embed product: Product, val size: Long) will be transformed to class Clothing(title: String, description: String, val size: Long) : Product(title, description)

[evanchooly]

one of my favorite features...

[rrader]

in your version I even don't need delegation
I can write class Clothing(val p: Product, val size: Long)

[rrader]

however, this is not desired

[bamdmux]

No, what delegation does

[bamdmux]

is that you can directly call the delegation entities

[bamdmux]

Assuming c is a Clothing, with delegation you can use c.name or c.description

[rrader]

even in Java?

[rrader]

For me it is more inconvenient on create object than using the object. I really want class to have the signature Clothing(title: String, description: String, val size: Long) : Product(title, description) but I don't want to duplicate everytime this part title: String, description: String and Product(title, description)

[bamdmux]

What do you mean "in Java"? The compiler will generate the java bytecode for the delegated methods

[bamdmux]

But if what you want is have a class with the constructor signature Clothing(name, desc, size)

[bamdmux]

Class delegation wouldnt do that for you

[rrader]

Thanks. Than it does not solve the issue.
