Implementation Proposal


Problem Statement :  

To publish the NcmpEvent when there is a change in the cmHandleState ( state transition )


Potential Solutions

  1. Use code triggers
  2. Any other solution ?


Solution #1 : Code Triggers


  • Identify all the possible cm handle state transitions.

  • Create a cmHandleState handler which takes in the cmHandleState transition event
    --  Responsible for identifying the state transition
    --  Based on state transition call the relevant methods to create the NcmpEvent accordingly.


  • Identify the trigger points in the code where the actual state transitioning is happening and call the handler from there and provide the type of transition.










  • No labels
