no match for call to ‘(std::vector<foo>) (std::vector<foo>::iterator&)’

Question

I've got a class foo, and have created a vector for it using this code

std::vector<foo> fooVector;

I also have an iterator using this code

std::vector<foo>::iterator locator;

now I'm getting this error

foo.cpp:29:25: error: no match for call to ‘(std::vector<foo>) (std::vector<foo>::iterator&)’

and the corresponding line is

if(fooVector(locator).getBoo() + (insertBar.geBoo()) < 4000)

as far as I can tell I'm using the iterator correctly?

I'm not sure what is wrong with how I'm using it?

Answer 1

fooVector(locator) what do you want to express by this?

fooVector is a variable not a function.

Answer 2

如果在使用locator器迭代器之前正确对其进行了初始化，则应将代码更改为

if(locator->getBoo() + (insertBar.geBoo()) < 4000)
