inheritance - Avoid using child method in parent class in python -


suppose have 2 classes in python below:

class parent(object):     def __init__(self):         self.num = 0      def fun1(self):         print 'p.fun1'      def fun2(self):         self.fun1()         print 'p.fun2'

and

from parent import parent  class child(parent):     def __init__(self):         super(child,self).__init__()      def fun1(self):         print 'c.fun1'      def fun2(self):         super(child, self).fun2()         print 'c.fun2'

and if call fun2 of child

from child import child  test = child() test.fun2()

i output:

c.fun1 p.fun2 c.fun2

which means call of child.fun2() leads parent.fun2(). inside parent.fun2(), use self.fun1() in case interpreted child.fun1() in test.

but want class parent individual , call of parent.fun2() uses parent.fun1() inside it.

how can avoid this?

i know can make parent.fun1() private parent.__fun1(). have instances of parent need use parent.fun1() outside class. means need override fun1().

that's how inheritance supposed work. behavior need, might want reconsider parent & child class's relationship, or change method names or @ least make parent methods classmethods or staticmethods.

this should work need, don't it.

class parent(object):     def __init__(self):         self.num=0     def fun1(self):         print 'p.fun1'     def fun2(self):         parent.fun1(self)         print 'p.fun2'

child class can remain same.

in classes accessed in inheritance chain, self point instance of class instantiated , not current class accessed in super call (or in order find method/attribute matter). self.fun2 point method of child class.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

How to understand 2 main() functions after using uftrace to profile the C++ program? -

android - Unable to generate FCM token from dynamically instantiated Firebase -

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
