Member Function Documentation

AddFlow()

void FlowStatMap::AddFlow	(	StationID	origin,
		StationID	via,
		uint	flow
	)

Add some flow from "origin", going via "via".

Parameters

origin	Origin of the flow.
via	Next hop.
flow	Amount of flow to be added.

Definition at line 5007 of file station_cmd.cpp.

DeleteFlows()

StationIDStack FlowStatMap::DeleteFlows

(

StationID

via

)

Delete all flows at a station for specific cargo and destination.

Parameters

via	Remote station of flows to be deleted.

Returns

IDs of source stations for which the complete FlowStat, not only a share, has been erased.

Definition at line 5069 of file station_cmd.cpp.

FinalizeLocalConsumption()

void FlowStatMap::FinalizeLocalConsumption

(

StationID

self

)

Subtract invalid flows from locally consumed flow.

Parameters

self	ID of own station.

GetFlow()

uint FlowStatMap::GetFlow

(

)

const

Get the sum of all flows from this FlowStatMap.

Returns

sum of all flows.

Definition at line 5111 of file station_cmd.cpp.

GetFlowFrom()

uint FlowStatMap::GetFlowFrom

(

StationID

from

)

const

Get the sum of flows from a specific station from this FlowStatMap.

Parameters

from	Origin station to look for.

Returns

all flows from 'from' added up.

Definition at line 5139 of file station_cmd.cpp.

GetFlowFromVia()

uint FlowStatMap::GetFlowFromVia	(	StationID	from,
		StationID	via
	)		const

Get the flow from a specific station via a specific other station.

Parameters

from	Origin station to look for.
via	Remote station to look for.

Returns

flow share originating at 'from' and going to 'via'.

Definition at line 5152 of file station_cmd.cpp.

GetFlowVia()

uint FlowStatMap::GetFlowVia

(

StationID

via

)

const

Get the sum of flows via a specific station from this FlowStatMap.

Parameters

via	Remote station to look for.

Returns

all flows for 'via' added up.

Definition at line 5125 of file station_cmd.cpp.

PassOnFlow()

void FlowStatMap::PassOnFlow	(	StationID	origin,
		StationID	via,
		uint	flow
	)

Pass on some flow, remembering it as invalid, for later subtraction from locally consumed flow.

This is necessary because we can't have negative flows and we don't want to sort the flows before adding them up.

Parameters

origin	Origin of the flow.
via	Next hop.
flow	Amount of flow to be passed.

Definition at line 5026 of file station_cmd.cpp.

ReleaseFlows()

void FlowStatMap::ReleaseFlows

(

StationID

via

)

Release all flows at a station for specific cargo and destination.

Parameters

via	Remote station of flows to be released.

Definition at line 5100 of file station_cmd.cpp.

RestrictFlows()

void FlowStatMap::RestrictFlows

(

StationID

via

)

Restrict all flows at a station for specific cargo and destination.

Parameters

via	Remote station of flows to be restricted.
