Prevent a subclass of a singleton class from calling the singleton's constructor
Category : Programming Languages

Ok, I have a singleton class GraphMaster which contains a number of system-wide values. I have a subclass GraphObject : GraphMaster which has graph specific data. By subclassing, I can access members of either the global class or subclass. And by using a singleton class, I can change the global variables anywhere and have them be reflected in all the subclasses.

Attempt to use my singleton that references another singleton
Category : Programming Languages

I'm calling my custom factory that I created (PhotoServiceFactory), which is a singleton that allows me to get at a specific custom service type back (in this case FacebookService). FacebookService is also a singleton. In FacebookService I've exposed an instance of FacebookAlbumPhoto through a property.

I'm using ActionScript3 to develop a Data Access Layer for an application another developer is working on in my team. One of the objects, lets call it User is expensive to construct. Each user has a unique ID number so I can tell if they've been created before or not, and all User objects are stored in an array somewhere else.

I want to be able to restrict
