> Improve configured method handling for ComponentFactory instances
> -----------------------------------------------------------------
>
> Key: FELIX-3569
> URL: https://issues.apache.org/jira/browse/FELIX-3569
> Project: Felix
> Issue Type: Improvement
> Components: Declarative Services (SCR)
> Affects Versions: scr-1.6.0
> Reporter: Felix Meschberger
> Assignee: David Jencks
> Fix For: scr-1.6.2
>
>
> Currently the ComponentFactory.newInstance method creates a new instance of
> an extension of the ImmediateComponentManager class to create a new component
> instance.
> Since configured methods to be called on the component (activator and bind
> methods) are maintained by these ImmediateComponentManager and its related
> DependencyManager instances, these methods are looked up over and over again
> for the same component class.
> In a web application using Sling's Rewriter which leverages ComponentFactory
> components to postprocess requests this amounts to a considerable number of
> repeated and needless reflection calls. This is particularly nasty in case of
> methods not existing.
> The same problem in fact also occurrs for components created due to factory
> configuration, where for each configuration instance a ComponentManager and
> its associated DependencyManagers is created to lookup the methods.
> We might want to come up with a centralized method accessor functionality
> which caches these methods and provides them to any ComponentManager and
> DependencyManager needing them.
