add a decorate function to a class
- by wiso
I have a decorated function (simplified version):
class Memoize:
def __init__(self, function):
self.function = function
self.memoized = {}
def __call__(self, *args, **kwds):
hash = args
try:
return self.memoized[hash]
except KeyError:
self.memoized[hash] = self.function(*args)
return self.memoized[hash]
@Memoize
def _DrawPlot(self, options):
do something...
now I want to add this method to a pre-esisting class.
ROOT.TChain.DrawPlot = _DrawPlot
when I call this method:
chain = TChain()
chain.DrawPlot(opts)
I got:
self.memoized[hash] = self.function(*args)
TypeError: _DrawPlot() takes exactly 2 arguments (1 given)
why doesn't it propagate self?
