You can create your own subscription class by implementing the IsMatch() method. This can be useful when you want to extend the options of defining the scope.

 

The diagram below illustrates inheritance of existing classes:

 

 

Choose one and inherit your subscription from it. Now you have to implement an override of the following method:

 

 

Your task is to evaluate whether the subscription or more precisely its properties (initialized in constructor) match the properties of obj and the value of taskType. Once they do, you simply initialize taskProcessType (which should be also initialized in constructor of subscription) and return true.
