Class design for calling "the same method" on different classes from one place
- by betatester07
Let me introduce my situation:
I have Java EE application and in one package, I want to have classes which will act primarily as cache for some data from database, for example:
class that will hold all articles for our website
class that will hold all categories
etc.
Every class should have some update() method, which will update data for that class from database and also some other methods for data manipulation specific for that data type.
Now, I would like to call update() method for all class instances (there will be exactly one class instance for every class) from one place.
What is the best design?
