[英]Use a base class method as a decorator in derived classes
I have come across a situation where I have a base class and multiple derived classes. 我遇到了一个基类和多个派生类的情况。 In each of the derived classes I am doing an action of extracting common data from input given to method.
在每个派生类中,我都在执行从提供给方法的输入中提取公共数据的操作。 Thus I have written that piece of code in base class as method so that derived classes could use it directly.
因此,我已在基类中将该代码段作为方法编写,以便派生类可以直接使用它。 But I want to call this function from each method where I want to perform this action.
但是我想从要执行此操作的每个方法中调用此函数。 My question is that can I write a decorator for this action?
我的问题是我可以为此动作编写装饰器吗? I want this decorator to be a member of base class.
我希望这个装饰器成为基类的成员。 Is it possible to use base class method as a decorator in derived classes?
是否可以将基类方法用作派生类中的装饰器?
Base class: 基类:
class BaseRequestHandler(object):
def __init__(self):
self.request=None
self.response=None
def extractheader(self,requestin):
##extracts header from incoming request
Derived class: 派生类:
class DerivedRequestHandler1(BaseRequestHandler):
def __init__(self):
super(DerivedRequestHandler1, self).__init__()
def handlermethod(self,requestin)
##extract headed
##call internal API with header
