    - #### XPRSoptNodeEvent

          void XPRSoptNodeEvent​(XPRSprob cbprob,
                                java.lang.Object cbdata,
                                IntHolder p_infeasible)

      Handle a `Optnode` event. More details about `Optnode` events can be found in the documentation of the corresponding C callback.
      Parameters:
        `cbprob` - The problem passed to the callback function, `optnode`.
        `cbdata` - The user-defined data passed as `data` when setting up the callback.
        `p_infeasible` - The feasibility status. If set to a nonzero value by the user, the current node will be declared infeasible.
