Blocks — Tue, 25 Jul 2023 08:24:46 +0000

1)sal-distributed-datastore:
A)ActorSystemProviderImpl

accepts a bundle context in the constructor to use the bundle's
classloader for reading Akka configuration. Also creates
a QuarantinedMonitorActor hard-coded to restart karaf (bundle_0:stop)
B)EntityOwnerSelectionStrategyConfigReader
deprecated, uses bundleContext to retrieve osgi config admin service,
then reads and parses the eos strategy config
C)DistributedDataStoreFactory
accepts bundle context in factory method to create DatastoreContextConfigAdminOverlay
D)DatastoreContextConfigAdminOverlay
gets config admin service via bundle context to listen on datastore config changes

2)sal-binding-broker
A)BindingToNormalizedNodeCodecFactory

registers a BindingToNormalizedNodeCodec instance as an osgi service. To quote jdoc:
"* This method is called via blueprint to register a BindingToNormalizedNodeCodec instance with the OSGI

service registry. This is done in code instead of directly via blueprint because the BindingToNormalizedNodeCodec
instance must be advertised with the actual class for backwards compatibility with CSS modules and blueprint
will try to create a proxy wrapper which is problematic with BindingToNormalizedNodeCodec because it's final
and has final methods which can't be proxied."
