Enumeration Type Documentation

DistributionType

enum DistributionType : uint8_t

Enumerator
DT_MANUAL	Manual distribution. No link graph calculations are run.
DT_ASYMMETRIC	Asymmetric distribution. Usually cargo will only travel in one direction.
DT_MAX_NONSYMMETRIC	Maximum non-symmetric distribution.
DT_SYMMETRIC	Symmetric distribution. The same amount of cargo travels in each direction between each pair of nodes.

EdgeUpdateMode

enum EdgeUpdateMode

Special modes for updating links.

'Restricted' means that vehicles with 'no loading' orders are serving the link. If a link is only served by such vehicles it's 'fully restricted'. This means the link can be used by cargo arriving in such vehicles, but not by cargo generated or transferring at the source station of the link. In order to find out about this condition we keep two update timestamps in each link, one for the restricted and one for the unrestricted part of it. If either one times out while the other is still valid the link becomes fully restricted or fully unrestricted, respectively. Refreshing a link makes just sure a minimum capacity is kept. Increasing actually adds the given capacity.

Enumerator
EUM_INCREASE	Increase capacity.
EUM_REFRESH	Refresh capacity.
EUM_RESTRICTED	Use restricted link.
EUM_UNRESTRICTED	Use unrestricted link.
