[aspectc-user] Pointcut & template class

[Olaf Spinczyk]

Hi,

the AspectC++ language does not allow you match templates, only template
*instances*. Therefore, what you problable mean is:

pointcut pippoPointcut() = "pippo<%>"; // matches all pippo instances

You could then give advice for all call to member functions of the
template by:

advice call(pippoPointcut()) : before () {
  cout << "pippo called" << endl;
}

However, please note that the template support in AspectC++ is still in
a very early state. The weaver cannot manipulate the template instances,
only non-template code. The advice above would only match calls that are
not located within the template itself. Also note that you will have to
compile with --real-instances.
