This is a convenience decorator to define a
before advice based on dcl.advise().
This is a shortcut function to define one
before advice. Logically it is defined as:
1 2 3 4 5
It means that instead of:
1 2 3
It is possible to write a shorter version:
This type of advice is a regular function. It is called with the same context and the same arguments as an advised method. Its return value is ignored.
It is not recommended to modify parameters inside
before advice. Use
around advice for that.
