Is it possible to overload operators in such a way that you can capture a specific combination of them? For example lets say I have a custom object myObject of type MyType where [] is already overloaded to pass such calls down to a map object. That said, in the case of the following code:
int value = myObject["someProp"];
I’m already overloading [] but in this case I’d like to know when [] is being called on the object in an assignment, with a reference to the type of object that the property lookup is to be assigned to. This way I can cast the value coming out of the dynamic property lookup and so on and so forth. Any input is appreciated!
For more insight into exactly what I’m trying to accomplish, see this related question of mine.
No, you can’t overload on the return type, or on the context in which the call appears (e.g. in an assignment etc).
You could, however, return a proxy object that would have a bunch of overloaded conversion operators. Without seeing what you intend to do, it’s hard to say how far you might be able to get with this approach, or whether it’s even a sane thing to do.
