angela commented on OAK-8155:
-----------------------------
[~stillalex], based on our discussion last week, i created another patch with a
slightly different approach not attaching the abort criteria to the
{{AggregatedPermissionProvider}} interface and ended up moving the evaluation
to a very early stage when computing the composite permission provider in the
{{CompositeAuthorizationConfiguration}}. feedback welcome as always.
> CompositePermissionProvider: add possibility to abort evaluation

> when aggregating multiple authorization models we currently have the ability
> to choose between CompositionType.AND and CompositionType.OR for the
> evaluation of effective permissions. In other words as soon as more than 1
> PermissionProvider is present for the evaluation the results of that
> evaluation are either combined in an AND or OR fashion.
> however, we currently lack the ability to stop or abort the evaluation if a
> given provider instance was 'sufficient' to determine if a given set of
> permissions is granted or denied.
> [~stillalex], let's discuss ideas and options on how we could achieve this.
