Can a ctor be declared inline ?
Is it not declared inline to avoid executable code size becoming
huge ?
kindly clarify
Thanks

Yes.

That may be a motive for someone.

Of course.

Usually, it's not declared inline to avoid unnecessary coupling.

Just curious, but coupling to what? I don't quite understand this.
Isn't the compiler obligated with ensuring that an inlined and non-
inlined function call are for the most part equivalent? To what
degree can an inlined function digress from a non-inlined version?
Or is it because that inline functions must be declared somehow in
each source file that uses the function (in this case a ctor), and
will typically be placed in a header, which arguably is the "wrong"
place to put the details of the code?

Note that inlining does not *always* increase executable code size.
It *may* reduce code size; it may increase code size. Please see: http://www.parashift.com/c++-faq-lit...s.html#faq-9.3

All code which needs to 'see' a class definition has also to 'see' all
inline members. Changing any of them forces recompilation which wouldn't
be necessary if they weren't inline.

I see; I suppose I haven't actually been on anything like a big C++
project (possibly involving library-in-binary-format), so I personally
don't care about recompilation; but I suppose this is a good idea, if
ever I get into one.

It doesn't have to. While defining the function inside the class
definition makes it inline, you can still just use the regular
"inline" keyword and define it elsewhere.

3.2.3 An inline function shall be defined in every translation unit in
which it is used.
So that 'elsewhere' usually is in the same header. Other places are hard
to maintain.

Nope. Only the places where it is used. Public methods are one
thing, but you said "all inline members" and there's no necessity to
expose them all if they can't be called everywhere the class
definition appears. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

will the third ctor in this class call the first two or just the null ctor?
