how to access [] operator in container class?

[tristen]

I'm writing a container class.

Is there a way to access the [] operator in the class itself, without dereferencing the this pointer?

ie: i'm finding i have to do this:

(*this)["blah"] = "123";

i can't seem to do this (compilation errors):

mycontainer::["blah"] = "123";

or this:

superclass::["blah"] = "123";

is the dereferencing necessary? i can live with it, but is it the most efficient way of doing it, performance-wise?

cheers

You have to. You can't access the current class in a function without using this, so you would have to deference it eventually.

if you don't want to explicitly dereference this you can call member operators as functions: operator[]("blah") = "123"

awesome bazzy, that's great, thanks.

Though that way you still dereference this, you just don't do it explicitly.

[tristen]

oh? sorry, i'm not sure what you mean, does the following dereference "this"?

this->operator[]("blah") = "123";

or should i be doing it a different way, maybe:

supercontainer::operator[]("blah") = "123";

this-> is the same as (*this).
