Hooks advice to a function or method.

advise() is a decorator that takes a set of functions or methods and injects the decorated function in their place. There is no concept of before/after callbacks. Instead, the intercepting function is responsible for calling (or not) the intercepted function.

The “classic” logging example:

class A(object):
  def a_function(self):
    print 'a_function()'

@advise(A.a_function)
def logit(on, next, *args, **kwargs):
  logging.debug('%r.%r(%r, %r)', on, next, args, kwargs)
  return next(*args, **kwargs)

See the function documentation for more information.
