使用其他类的方法的类c ++

Question

I have two classes, A , and B . They are declared thusly:

class A
{
    public: void function() throw (exception);
};

class B
{
    public: void function();
};

B::function calls A::function . Inside B::function , I want to suppress the exception that A::function sometimes throws, and continue execution afterwards. How do I do this?

Answer 1

You can drop all exceptions using try { .. } catch ( ... ) { } :

void ClassB::doSomething()
{
    try {
        classAObject.doSomethingWhichMayThrow();
    } catch ( ... ) {
    }
}

Please note that this may have moral implications. You should be ready to explain (at least in a comment of the code) why swallowing exceptions at this point is acceptable.
