Table of function pointers within a class C++

Question

I'm trying to make a table of function pointers within a class. I haven't been able to find any examples of this online, most involve using member function pointers outside of their class.

for example:

class Test
{
    typedef void (Test::*FunctionType)();
    FunctionType table[0x100];

    void TestFunc()
    {
    }

    void FillTable()
    {
        for(int i = 0; i < 0x100; i++)
            table[i] = &Test::TestFunc;
    }   

    void Execute(int which)
    {
        table[which]();
    }
}test;

Gives me the error "term does not evaluate to a function taking 0 arguments".

Answer 1

In this line in the Execute function:

table[which]();

You can't call it like that because it's not a normal function. You have to provide it with an object on which to operate, because it's a pointer to a member function, not a pointer to a function (there's a difference):

(this->*table[which])();

That will make the invoking object whichever object is pointed to by the this pointer (the one that's executing Execute).

Also, when posting errors, make sure to include the line on which the error occurs.

Seth has the right answer. Next time, look up the compiler error number on MSDN and you'll see the same: Compiler Error C2064.
