MrpRelationType mrp_relation_get_relation_type (MrpRelation *relation);
A predecessor relation is used to affect the scheduling of a task relative another task. A relation may have a lag time associated to it, so that a task can be scheduled to start after another task has finished, plus a lag time.
typedef struct _MrpRelationPriv MrpRelationPriv;
A private struct for internal use only. The definition of this structure is not publically available.
struct MrpRelation {
MrpObject parent;
MrpRelationPriv *priv;
};
Object representing a predecessor relation between two tasks.

} MrpRelationType;
The type of relation.
MrpTask * mrp_relation_get_predecessor (MrpRelation *relation);

Returns : |
the successor task. |
gint mrp_relation_get_lag (MrpRelation *relation);
