Scott Deboy commented on LOG4J2-191:
------------------------------------
I'm finding a couple of places where the plugin keys are used..but I don't
really want to expose the key implementation (a helper class with hash code and
equals representing the plugin name and element type).
Both interpolator and flume use the keys from getPlugins....I think I'd prefer
to add the plugin name to the PluginType and then expose a list, instead of a
map, from PluginManager#getPlugins.
Thoughts?

> I have a default/no-op 'advertiser' implementation:
> @Plugin(name = "default", type = "Core", elementType = "advertiser",
> printObject = false)
> public class DefaultLeftOut implements Advertiser {
> If some other person names another plugin as 'default' in core or even under
> a different 'type' (admittedly default is a terrible name and I should rename
> it)...we will have a problem.
> I think the element type should be part of the resolution..
> Still using:
> PluginManager pluginManager = new PluginManager("Core");
> pluginManager.collectPlugins();
> But instead of code using:
> PluginType type = getPluginManager().getPluginType(name);
> (with name = 'default' in this Advertiser case, giving me a DefaultAdvertiser)
> Maybe:
> PluginType type = getPluginmanager().getPluginType(elementType, name);
> (with elementType = 'advertiser' and name = 'default' in this advertiser case)
> In theory, we should also update the Maps in pluginmanager to support this
> uniqueness...right now we collide just on 'name' in the type.
> Right now, the last one wins, which isn't ideal.
> At least we'd reduce the likelihood of collisions.
> Along with passing in type type and name in the lookup, collisions of name
> and type (another 'default' in 'core') should be logged at warn level. I
> suppose last one registered should still win.
