How do I declare a method that returns a pointer to a function?

How do I declare a method that returns a pointer to a function?

The following method takes parameter a char and returns a pointer to a function. To
avoid this heavy syntax, you may use a typedef.
struct A
{
void (*m(char))(int) { /* ... */ }
};
// ...
A a;
void (*pf)(int);
pf = a.m('a');

How can I handle easily a pointer to a method?

How can I handle easily a pointer to a method?

If you use templates, you won't have to write the annoying type of a pointer to a method (at the 'cost' of using a template). You can also use typedef to declare the type.

struct A
{
void m() {}
};
template
void f(A &a
8
PMETHOD pm)
{
(a.*pm)()
}
void function()
{
A a;
f(a, &A::m);
}

How do I declare, assign and call a pointer to a method?

How do I declare, assign and call a pointer to a method?

Note that a pointer to a method does not hold a second pointer to an instance of a
class. To use a pointer to a method, you need an instance of the class onto which this
method can be called (possibly a second pointer).

struct A
{
void m(int) {}
};
void function()
{
void (A::*pm)(int) = &A::m; // pointer on method
A a; // instance of a class
(a.*m)(1); // calling the method with parameter value 1.
}

How do I put the code of methods outside classes in a header file?

How do I put the code of methods outside classes in a header file?

The code of a method specied in a header le must be declared inline. It means that when compiling, the calls to the method will all be replaced by the code of that method.

struct A
{
int a;
A();
};
inline A::A()
{
/* ... */
};
