Detailed Description

template<class ParamT>
class Callbackable< ParamT >

This template contains convenience functions to be inherited by classes pro- viding callback functionality. You can use this as a base class providing the callback parameter your class is going to process. Users of your class can profit from the static MakeCallback resp. MakeClosure methods to generated Callback objects. Later they can easily be passed back to your class.

Note: the convenience methods return a pointer to a callback object. The user is responsible to clean up those pointers in some way. If it is a one- time callback, it makes sense to delete it inside the inheriting class once it was invoked.

TODO: C++11 - Replace this functionality by lambdas

Parameters

ParamT

the parameter type of the callbacks to be called

static CallbackTN* Callbackable< ParamT >::MakeCallback ( typename Callback< ParamT >::CallbackFunction  function )

inlinestatic

Produces a Callback object that invokes a static function or a globally de- fined C-like function.

Parameters

function

Function pointer to the function to be invoked
