Public Member Functions | |
| SymmetricScaler (uint mod_size) | |
| Constructor. | |
| void | AddNode (const Node &node) |
| Count a node's supply into the sum of supplies. | |
| void | SetDemandPerNode (uint num_demands) |
| Calculate the mean demand per node using the sum of supplies. | |
| uint | EffectiveSupply (const Node &from, const Node &to) |
| Get the effective supply of one node towards another one. | |
| bool | HasDemandLeft (const Node &to) |
| Check if there is any acceptance left for this node. | |
| void | SetDemands (LinkGraphJob &job, NodeID from, NodeID to, uint demand_forw) |
| Set the demands between two nodes using the given base demand. | |
Private Attributes | |
| uint | mod_size |
| Size modifier. Determines how much demands increase with the supply of the remote station. | |

Get the effective supply of one node towards another one.
In symmetric distribution the supply of the other node is weighed in.
| from | The supplying node. |
| to | The receiving node. |

Check if there is any acceptance left for this node.
In symmetric distribution nodes only accept anything if they also supply something. So if undelivered_supply == 0 at the node there isn't any demand left either.
| to | Node to be checked. |

| void SymmetricScaler::SetDemands | ( | LinkGraphJob & | job, |
| NodeID | from_id, | ||
| NodeID | to_id, | ||
| uint | demand_forw | ||
| ) |
Set the demands between two nodes using the given base demand.
In symmetric mode this sets demands in both directions.
| job | The link graph job. |
| from_id | The supplying node. |
| to_id | The receiving node. |
| demand_forw | Demand calculated for the "forward" direction. |
