Hi, what could be reason of not creating proper method

MessageApi.prototype.onMessage_ep0k5p$ = function (listener) {
    this.socketApi_0.addListener_lgim5c$(KWebSocket$Companion_getInstance().EVENT_MESSAGE, MessageApi$onMessage$lambda(listener));
  };

This was not created:

Object.defineProperty(MessageApi.prototype, 'onMessage', {
    get: function () {
      return this.onMessage_ep0k5p;
    }
  });

This is the class:

class MessageApi(private val socketApi: ISocketApi, override val user: String = WebAppUser) : IMessageApi {

    override fun onMessage(listener: MessageListener) {
        socketApi.addListener(KWebSocket.EVENT_MESSAGE) {
            it.data?.apply {
                listener(this)
            } ?: println("Message text was null: $it")
        }
    }

    override fun send(text: String) {
        socketApi.webSocket.send(SocketData(SocketDataType.Default, user, KWebSocket.EVENT_MESSAGE, text))
    }
}

If I got your point the reason is Object.defineProperty is used for property accessors but in your case onMessage is method, not a property.

Ok, but I dont have visible onMessage_ep0k5p from javascript

[fair_enough]

i have method onMessage on class MessageApi. So I had to hack it by adding this property accessor

[fair_enough]

For instance compare those methods:

ContentApi.prototype.on_taqqg7$ = function (listener) {
    this.socketApi_0.addListener_lgim5c$(KWebSocket$Companion_getInstance().EVENT_CONTENT, ContentApi$on$lambda(listener));
  };
  ContentApi.prototype.test = function () {
    println_0();
  };

[fair_enough]

interface ITest {
    fun test()
}

class ContentApi(private val socketApi: ISocketApi) : IContentApi, ITest {

    override fun on(listener: (IContentItem) -> Unit) {
        socketApi.addListener(KWebSocket.EVENT_CONTENT) {
            it.data?.apply {
                listener(JSON.parse<ContentItem>(this))
            } ?: println("Content item was null: $it")
        }
    }

    override fun test() {
        println()
    }

}

And compiled interface is:

ContentApi.$metadata$ = {
    kind: Kind_CLASS,
    simpleName: 'ContentApi',
    interfaces: [ITest, IContentApi]
  };
  function IContentApi() {
  }
  IContentApi.$metadata$ = {
    kind: Kind_INTERFACE,
    simpleName: 'IContentApi',
    interfaces: []
  };

[fair_enough]

I presume 'ContentApi.prototype.on_taqqg7$', the suffix '_taqqg7$' is alias for internal use. but I need it public

[fair_enough]

without suffix

[fair_enough]

And for some cases it works, for some don't

[Roman Artemev [JB]]

I see, the reason for such weird suffix is because the stable name is required. If you need a clear name please try annotate onMessage with JsName("onMessage")

[fair_enough]

Thank you really much.
