        int XPRSslpDrColEvent​(XPRSprob cbprob,
                      java.lang.Object data,
                      int col,
                      int detcol,
                      double detval,
                      DoubleHolder p_value,
                      double lb,
                      double ub)
        Handle a SlpDrCol event. More details about SlpDrCol events can be found in the documentation of the corresponding C callback.
        Parameters:
        cbprob - The problem passed to the callback function.
        data - The user-defined object passed as data to addCbSlpCascadeVar.
        col - The index of the column for which the determining columns is checked.
        detcol - The index of the determining column for the column that is being updated.
        detval - The value of the determining column in the current SLP iteration.
        p_value - Used to return the new value for column col, should it need to be updated, in which case the callback must return a positive result to indicate that this value should be used.
        lb - The original lower bound of column col. The callback provides this value as a reference, should the bound be updated or changed during the solution process.
        ub - The original upper bound of column col. The callback provides this value as a reference, should the bound be updated or changed during the solution process.
