Python Decorator

下述使用myDecorator的__call__方法替换aFunction:

class myDecorator(object):

def __init__(self, f):

print("inside myDecorator.__init__()")

f() # Prove that function definition has completed

def __call__(self):

print("inside myDecorator.__call__()")

@myDecorator

def aFunction():

print("inside aFunction()")

print("Finished decorating aFunction()")

aFunction()
