没有匹配'（std :: vector <foo> ）（std :: vector <foo> :: iterator＆）'

Question

I've got a class foo, and have created a vector for it using this code 我有一个foo类，并使用此代码为其创建了一个向量

std::vector<foo> fooVector;

I also have an iterator using this code 我也有一个使用此代码的迭代器

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

now I'm getting this error 现在我得到这个错误

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

and the corresponding line is 相应的行是

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

as far as I can tell I'm using the iterator correctly? 据我所知，我正确使用了迭代器？

I'm not sure what is wrong with how I'm using it? 我不确定我的使用方式有什么问题？

Answer 1

fooVector(locator) what do you want to express by this? fooVector(locator)您要表达什么？

fooVector is a variable not a function. fooVector是变量而不是函数。

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)

没有匹配&#39;（std :: vector <foo> ）（std :: vector <foo> :: iterator＆）&#39;
