Function Documentation

bool CheckSharingChangePossible ( VehicleType  type  ) 

Check if a sharing change is possible.

If vehicles are still on others' infrastructure or using others' stations, The change is not possible and false is returned.

Parameters:
type The type of vehicle whose setting will be changed.
Returns:
True if the change can take place, false otherwise.

void HandleSharingCompanyDeletion ( Owner  owner  ) 

Handle the removal (through reset_company or bankruptcy) of a company.

i.e. remove all vehicles owned by that company or on its infrastructure, and delete all now-invalid orders.

Parameters:
Owner the company to be removed.

static bool OrderDestinationIsAllowed ( const Order *  order,
const Vehicle *  v,
Owner  owner = INVALID_OWNER 
) [static]

Check whether an order has a destination that is allowed.

I.e. it refers to a station/depot/waypoint the vehicle is allowed to visit.

Parameters:
order The order to check
v The vehicle this order belongs to.
owner Owner whose infrastructure is not allowed, because the company will be removed. Ignored if INVALID_OWNER.
Returns:
True if the order has an allowed destination.
