- Public Member Functions inherited from CYapfBaseT< RiverBuilderTypes >
 CYapfBaseT ()
 default constructor
 
 ~CYapfBaseT ()
 default destructor
 
const YAPFSettings & PfGetSettings () const
 return current settings (can be custom - company based - but later)
 
bool FindPath (const VehicleType *v)
 Main pathfinder routine:
 
Node * GetBestNode ()
 If path was found return the best node that has reached the destination.
 
Node & CreateNewNode ()
 Calls NodeList::CreateNewNode() - allocates new node that can be filled and used as argument for AddStartupNode() or AddNewNode()
 
void AddStartupNode (Node &n)
 Add new node (created by CreateNewNode and filled with data) into open list.
 
void AddMultipleNodes (Node *parent, const TrackFollower &tf)
 add multiple nodes - direct children of the given node
 
void AddNewNode (Node &n, const TrackFollower &follower)
 AddNewNode() - called by Tderived::PfFollowNode() for each child node.
 
const VehicleType * GetVehicle () const
 
void DumpBase (DumpTarget &dmp) const
 
- Public Member Functions inherited from CYapfSegmentCostCacheNoneT< RiverBuilderTypes >
bool PfNodeCacheFetch (Node &)
 Called by YAPF to attach cached or local segment cost data to the given node.
