| /** |
| * Provides interfaces to build and obtain YANG data tree which is data |
| * (sub)instance representation, abstract of protocol. |
| * |
| * NBI protocol implementation takes care of the protocol specific |
| * operations. They are abstracted from the intricacies of understanding |
| * the application identification or handling the interaction with |
| * applications. |
| * |
| * NBI protocols need to handle the encoding and decoding of data to the |
| * protocol specific format. They are unaware of the YANG of applications, |
| * i.e. protocols are unaware of the data structure / organization in |
| * applications. |
| * |
| * They need to translate the protocol operation request, into a protocol |
| * independent abstract tree called the YANG data tree (YDT). In order to |
| * enable the protocol in building these abstract data tree, YANG |
| * management system provides a utility called the YANG data tree builder. |
| * |
| * Using the YANG data tree utility API's protocols are expected to walk |
| * the data received in request and pass the information during the walk. |
| * YANG data tree builder, identifies the application which supports the |
| * request and validates it against the schema defined in YANG, and |
| * constructs the abstract YANG data tree. |
