interface GroupPermissionCalculatorInterface in Group 8

Defines the group permission calculator interface.

Please make sure that when calculating permissions, you attach the right cacheable metadata. This includes cache contexts if your implementation causes the calculated permissions to vary by something. Any cache contexts defined in the getPersistent...CacheContexts() methods will automatically be added to the corresponding calculated permissions.

It's of the utmost importance that you properly declare any cache context that should always be present in the _CACHE_CONTEXTS constants. For instance: If your outsider permissions are the same for everyone but user 1337, then your outsider permissions must ALL vary by the user cache context.

Do NOT use the user.group_permissions in any of the calculations as that cache context is essentially a wrapper around the calculated permissions and you'd therefore end up in an infinite loop.
