[aspectc-user] Aspect data members

[Olaf Spinczyk]

Hi Francisco,

if you tried the same with a C++ class instead of an aspect, the C++ compiler
would complain as well. The problem is that you can't create an attribute with a
constructor argument as you did it ("Test xyz(99)"). The only way to pass a
constructor argument to an attribute instance is via the constructor of the
aggregating class:

aspect myAspect {
  Test xyz;
public:
  myAspect () : xyz (99) {}
  ...
};

This should work (haven't tried).

Best regards,

Olaf
