Ksubscribe library for Python Coders

This is a library that help python coder to run event-based methodology.

You can subscribe an event from object to another object. Ksubscribe library is designed with Singleton design pattern. So, if you create more that one Ksubscribe object, the all object is actually same object.

!!!!

Firstly, subscriber can subscribe an any event that is created before. After this operation, subscriber class must have inform functions.

You can see the inform function in below. Subscribed classc can send only one parameter that can be list, dict etc.

    def inform(self,eventName,parameters=None)

You can publish the event from subscriber like this from subscribed class

    self.slaveEventObject = Ksubscribe()
    def eventTwoSecond(self):
        self.slaveEventObject._publish(eventName="everyTwoSecond")

The ksubscribe library has these function that is mentioned in below.

    def _subscribeForAnEvent(self,subscriber,eventName:str)
       If this function returns True, subsciption is built.
       If this function returns False, subscription is not built.


    def _createAnEvent(self, eventName:str)
       If this function returns True, event is created.
       If this function returns False, event is not created.


    def _publish(self,eventName:str,parameters=None)
        This function does not return any value.


    def _removeAnEvent(self,eventName:str)
        If this function returns True, event is removed from event list.
        If this function returns False, event is not removed from event list


    def _removeAllEvents(self)
        If this function returns True, all events are removed.
        If this function returns False, all events are not removed.
    

    def _removeSubscriberFromEvent(self,subscriber, eventName:str)
        If this function returns True, subscriber is removed from event's subscriber list.
        If this function returns False, subscriber is not removed from event's subscriber list.
