From singleton to simpleton

[nicolasdanet]

Could it be possible to generate an unique key for each instance of the plugin, and then fetch related data with that key in a global shared instance? It might be clunky to achieve thread safety and such, but after all it is just a map of few pointers.

Note that I’m not familiar with plugin dev thus it can be a totally dumb approach.

Create singleton for each plugin instance

I have a singleton in my plugin, which distributes wavetables to the audio classes. Now i’m running into problems, since multiple instances are sharing data, which they really shouldn’t. I know how to resolve the issues by making it not a singleton and attaching one to each pluginprocessor, but it is a considerable amount of work. Hence the question: Is there a way to make each instance use its own singleton?

Singleton instance shared between plugin instances

I am using JUCE’s implementation of singletons for having a centralized data store for my plugin. When running more than one instance of my plugin in the same DAW, the singleton instance is the same between them. Is this because of how static fields operate in context of plugins? Is there a way to use the singleton paradigm without the singleton instance being the same with all plugin instances?

Note that if you can avoid that it is better. You could just pass the adress of the stuff into the constructor of your objects to store them as a (reference) (usually named owner) member. In that case life-time must be extra double checked. But IMHO most of time the overall main class remains from start to end, thus is easy to manage.
