int for example the ApiManager.INSTANCE.doSomething(), can we override the INSTANCE getter function?

[gildor]

What is your use case for this?

[Mohamed Ibrahim]

I want to check if a variable is initialized inside that class

[Sergio C.]

::something.isInitialized

[gildor]

You cannot override object instance directly. Check it in doSomething()
Or alternatively expose this object using own property that would check a variable

[gildor]

But in general this approach smells, same as most of usages of Singleton pattern with initialization

[Mohamed Ibrahim]

yes but Object is a Singleton which may depend on something that is not there yet

[gildor]

Yes, I got your case, and saying that you can do check using special getter function, just abstract actual object, but Singleton with initialization sounds as antipattern and you probably should use standard class with constructor instead

[Kris Wong]

sounds like a job for DI or service locator
