stop it with constexpr everything
on the reverse, you should make as much constexpr as you can

Constexpr is just a subtle hint to the compiler. constexpr clutterd code
BinaryByter
it clutters code A LOT
BinaryByter
so IMHO, atleast in time insensitive applications, constexpr everything is bs
BinaryByter
+ the compiler optimizes alot by itself already

Constexpr is just a subtle hint to the compiler. constexpr clutterd code
constexpr is not a subtle hint, it is a property that is transitive
BinaryByter
Measured with time?
BinaryByter
time isnt too accurate, tbh
Ludovic 'Archivist'
Oh?
a whole cascade of constant expressions can affect very complex computations
MᏫᎻᎯᎷᎷᎬᎠ
Mark the function with const
BinaryByter
a whole cascade of constant expressions can affect very complex computations
I see... But isnt there a way to add it more subtly?
MᏫᎻᎯᎷᎷᎬᎠ
getArea() const

I see... But isnt there a way to add it more subtly?
not while keeping constant expressiveness that can be used in templates too
Ludovic 'Archivist'
constexpr int getArea() const{
return _h*_w;
}

MᏫᎻᎯᎷᎷᎬᎠ
You have to mark your function with const so that it confirm you are not changing anything
Ludovic 'Archivist'
Constexpr is a compile time thing
not exactly, it means the expression is devoid of side effects on any element
BinaryByter
not exactly, it means the expression is devoid of side effects on any element
But what IF it does have those side effects?
BinaryByter
will the compiler still constexpr stuff?
BinaryByter
I should get into constexpr more

This sentence is grammatically correct, right?!
MᏫᎻᎯᎷᎷᎬᎠ
Read C++ standards
And take it as a reference

Not by value lol

what should i write instead of this?

newAttributesList[i][j][k] = uno::makeAny( (sal_Int32)Value );

i tried * and & in the frond of

No

3 indexes are bad
MᏫᎻᎯᎷᎷᎬᎠ
Are those types?
MᏫᎻᎯᎷᎷᎬᎠ
MᏫᎻᎯᎷᎷᎬᎠ
Like
You cannot convert int* to int
MᏫᎻᎯᎷᎷᎬᎠ
Whatever your type is
MᏫᎻᎯᎷᎷᎬᎠ
newAttributesList[i][j][k] = uno::makeAny( (sal_Int32)Value );
that means makeAny returns a pointer of type Any
BinaryByter
imho

You can't reserve something on the heap to the stack
MᏫᎻᎯᎷᎷᎬᎠ
Probably he is practicing

yes

eww

design patterns
BinaryByter
design patterns are antipatterns

xDD
BinaryByter
Yup
MᏫᎻᎯᎷᎷᎬᎠ
You can't reserve something on the heap to the stack
You are like saying
int x[1] = new int;
MᏫᎻᎯᎷᎷᎬᎠ
It seems awesome
