Hi,

What's the best way to abstract out the fromJson functionality so that it can be re-used? There doesn't seem to be a way to do it using interfaces that I can find...

data class MyClass(val type: String) {
    companion object {
        fun fromJson(j: String) = Gson().fromJson(j, MyClass::class.java)
    }
}

data class MyOtherClass(val type: String) {
    companion object {
        fun fromJson(j: String) = Gson().fromJson(j, MyOtherClass::class.java)
    }
}

not sure what exactly you want but this seems pretty reusable

inline fun <reified T> String.fromJson(): T = Gson().fromJson(this, T::class.java)

thanks, i was looking for valid syntax to include the function in an interface, but this works too
