#ifndef __CALLER__H__
#define __CALLER__H__
/* The templates below can be auto generated by tools/create_templates.pl.
* They are used to represent a functor with a given number of parameters and
* a specific return type. To prevent passing the wrong number of parameters
* and have the compiler detect this error at build-time, each class is numbered
* according to the number of parameters it takes, e.g. caller0, caller1, caller2.
* These have been generated from zero parameters to eight.
*
* If you want to declare a functor which takes two parameters, a User and a Channel,
* and returns bool, simply create it like this:
*
* caller2<bool, User*, Channel*> MyFunction;
*
* and initialize it correctly, when placed into a class you will be able to call it:
*
* bool n = someclass->MyFunction(someuser, somechan);
*
* These functor templates work this way so that you can simply and easily allow
* for these class methods to be overridden from within a module, e.g. have a module
* which completely replaces the code f r IsNick, etc. For example, with the example
* above:
*
* MyNewFunction replaceme(ServerInstance);
*
* someclass->MyFunction = &replaceme;
*
* After this point, calls to someclass->MyFunction will call the new code in your
* replacement functor.
*
* This is a very powerful feature which should be considered 'advanced' and not for
* beginners. If you do not understand these templates, STAY AWAY from playing with
* this until you do, as if you get this wrong, this can generate some pretty long
* winded and confusing error messages at compile time.
