Model-Driven Service Abstraction Layer (MD-SAL)¶
Overview¶
MD-SAL provides infrastructure for binding YANG models to Java object model and infrastructure for providing YANG-defined interaction patterns: * Reactive datastore update * RPC and Action invocation * Notification sourcing and delivery
Behavior/Feature Changes¶
The Binding mapping of type bits YANG statement has been updated to use a dedicated common
superinterface, BitsTypeObject. Furthermore individual bits within these classes are now represented
as primitive boolean values rather than nullable Boolean objects.
New Features¶
Both DOMRpcProviderService and RpcProviderService have gained the ability to register single-type
and flexible multi-type RPC implementations. RpcConsumerRegistry have gained the ability to access single-RPC
handles. These capabilities are based on new codegen feature, which generates @FunctionalInterface interfaces
for each individual rpc, similar to how action statements are processed.
Binding code generator now recognizes RFC8040 rc:yang-data extensions and generates corresponding interfaces.
Deprecated Features¶
NotificationService.registerNotificationListener() method has been deprecated, along with its Binding
specification interfaces based on NotificationListener. These will be removed in a future major release.
RpcProviderService.registerRpcImplementation() methods, RpcConsumerRegistry.getRpcService() methods and
Binding specification interfaces based on RpcService have been deprecated. These will be removed in a future
major release.
Removed Features¶
No removed features.
