HashMap.erase(Iterator it) makes "it"'s value uncertain?

[Poechant]

Code: Select all

Poco::HashMap<std::string, MediaConnector*>::Iterator it = myMap.find(key);
myMap.erase(it);
std::cout << it->first << " " << it->second << std::endl;

I find that

Code: Select all

it->first

and

Code: Select all

it->second

could generate correct values generally.
But sometimes

Code: Select all

it->first

and

Code: Select all

it->second

are uncertain values or undefined staffs.

That is to say, it's not reliable to use the iterator after using it as a parameter in the HashMap::erase(Iterator it) function, right?

Right.
