Clearing singletons

[Jamie Salvatori]

From time to time, we have to make small changes to CFCs that are loaded as singletons on our production server. We don't want to do a framework reinit on the production site, so what's the simplest programmatic way to clear a particular singleton and have it reloaded?

Would it be something like:

wirebox.getScopes()["SINGLETON"].getSingletons().remove(keyOfSingletonToRemove)

Has anybody implemented something like this? Or is there a better or more accepted way to do this on a production server?

TIA
Jamie

The injector has a method called clearSingletons()  so just do 

 

wirebox.clearSingletons();

 

I've never cleared a single singleton, but your code below will probably work.

 

However, PLEASE NOTE, that if you have injected a reference to your singleton into another CFC, that CFC will still keep its original reference.  

 

Thanks!

Is there a way to clear the references to the singletons that have been injected?

You could wrap every single injection in a provider.

 

property name="myService" inject="provider:myService";

 

It's a little messy but it would work because it asks WireBox for the instance every time.  

Thanks!
