Class execution

[Riaan]

Hi Everybody,

How do I stop my class of being used after certain init functions failed in
my constructor ?

Call abort or use an assert. There is no other generic way.

I'll try :)

The generic solution is to throw an exception.
"use an assertion" is one form of throw an exception.

class Monkey {
public:
class InitError {}; // Just a dummy type

Monkey(int a)
{
if ( !a )
{
throw InitError();
}
}
};

int main()
{
try {
Monkey ape;
}
catch( InitError const k )
{

}
}

Unchecked code, may contain errors/bugs.

catch( InitError const k )

catch ( Monkey::InitError const k)

I'm not just a number. To many, I'm known as a string...

AFAIK 'using an assertion' is NOT a form of 'throwing an exception'.
Exceptions can be caught, assertions cannot. Assertions will abort your
program if the fail.
