rpl_rank_t(* rpl_of::calculate_rank)(rpl_parent_t *, rpl_rank_t)

Calculates a rank value using the parent rank and a base rank.

If "parent" is NULL, the objective function selects a default increment that is adds to the "base_rank". Otherwise, the OF uses information known about "parent" to select an increment to the "base_rank".

Definition at line 192 of file rpl.h.

void(* rpl_of::neighbor_link_callback)(rpl_parent_t *, int, int)

Receives link-layer neighbor information.

The parameter "known" is set either to 0 or 1. The "etx" parameter specifies the current ETX(estimated transmissions) for the neighbor.

Definition at line 177 of file rpl.h.

void(* rpl_of::reset)(struct rpl_dag *)

Resets the objective function state for a specific DAG.

This function is called when doing a global repair on the DAG.

Definition at line 171 of file rpl.h.

void(* rpl_of::update_metric_container)(rpl_instance_t *)

Updates the metric container for outgoing DIOs in a certain DAG.

If the objective function of the DAG does not use metric containers, the function should set the object type to RPL_DAG_MC_NONE.
