I want to know why I have to pass dataManager(instance of DataManager), I only want that when I call getData() ,then at call time I have to pass function of DataManager that takes only parameter WebDataListener<T>

[edwardwongtl]

Because the type of func is DataManager.(Listener) -> Unit, you have to specify which DataManager is used to receive the .(Listener) -> Unit function call

[Kulwinder Singh]

ok I got it

[Kulwinder Singh]

but one last thing I want to know is that,i only want to perform function call of func() in getData() but I also have to specify it parameters when I am calling getData()

[edwardwongtl]

I don't quite get what you mean, could you explain a bit?

[edwardwongtl]

getData(listener) {} is what you need to call getData(), you don't have to pass a DataManager into the lambda

[Kulwinder Singh]

i only want to call HighOreder (func) inside getData() function, but when i calling getData() then i am asked to call func like getData(otherParams){ BaseDataDelegation(this,listener)// i don't want to call it here}

[edwardwongtl]

The point of higher order function is that the caller don't need to know the function impl, the impl is provided by the caller

[Kulwinder Singh]

but can i use method refrence here like DataManger::functionName , actully i have used this and its working , i want your advice

[edwardwongtl]

That's the correct way I think

[Kulwinder Singh]

yea its working correctly but i don't have any Refrence of it so therefore i'm doubting this and not sure about it
