Interface YdtWalker

All Known Subinterfaces:

All Known Implementing Classes:

DefaultYdtWalker

public interface YdtWalker

Abstraction of an entity which provides interfaces for YDT walk. When YANG management system gets data from application to be returned to protocol for any protocol operation or as a part of notification, YANG management system encodes this data in a YANG data tree and sends the same to protocol. Protocols can use the YANG data tree walker utility to have their callbacks to be invoked as per the YANG data tree walking. By this way protocols can encode the data from abstract YANG data tree into a protocol specific representation. YDT walker provides entry and exit callbacks for each node in YANG data tree.

Method Summary

Modifier and Type	Method and Description
void	walk(YdtListener ydtListener, YdtContext rootNode) Walks the YANG data tree.

Method Detail

walk

void walk(YdtListener ydtListener,
          YdtContext rootNode)

Walks the YANG data tree. Protocols implements YDT listener service and walks YDT tree with input as implemented object. YDT walker provides call backs to implemented methods.

Parameters:

ydtListener - YDT listener implemented by the protocol

rootNode - root node of YDT
