Interface FWMapView<NODE>

Deprecated.

@Deprecated
public interface FWMapView<NODE>

This interface provides additional information about the map Floyd-Warshall algorithm is going to work with.

Generally, you will use FWMap interface to define the map in general and then use this FWMapView interface to specify a specific needs you need to impose over the map as is "forbidding" some nodes or "imposing additional costs onto the nodes".

Method Summary

int	getEdgeExtraCost(NODE nodeFrom, NODE nodeTo) Deprecated. Method defining extra-edge cost, similar to AStarEvaluator.getExtraCost(Object, Object).
int	getNodeExtraCost(NODE node) Deprecated. Method defining extra-node cost, that is a cost that is attached to the "node", by having such node on the path costs This allows you to provide "customization" to the graph nodes, basicly it is a way of telling "this node is cool to have in path" (negative cost) or "this node is bad to have in path" (positive cost).
boolean	isEdgeOpened(NODE nodeFrom, NODE nodeTo) Deprecated. Method defining which "edges" (oriented links between nodes) can be used for the purpose of path-planning.
boolean	isNodeOpened(NODE node) Deprecated. Method defining which nodes are allowed to be explored / used by FloydWarshall for the purpose of path planning.

Method Detail

getNodeExtraCost

int getNodeExtraCost(NODE node)

Deprecated.

Method defining extra-node cost, that is a cost that is attached to the "node", by having such node on the path costs This allows you to provide "customization" to the graph nodes, basicly it is a way of telling "this node is cool to have in path" (negative cost) or "this node is bad to have in path" (positive cost).

Parameters:

nodeFrom -

nodeTo -

Returns:

getEdgeExtraCost

int getEdgeExtraCost(NODE nodeFrom,
                     NODE nodeTo)

Deprecated.

Method defining extra-edge cost, similar to AStarEvaluator.getExtraCost(Object, Object). This allows you to provide "customization" to the graph edge lengths. It allows you to say "this is a cool edge to use for travel" (negative extra cost) or "this edge is hard to cross" (positive extra cost).

Parameters:

nodeFrom -

nodeTo -

Returns:

isNodeOpened

boolean isNodeOpened(NODE node)

Deprecated.

Method defining which nodes are allowed to be explored / used by FloydWarshall for the purpose of path planning. May be used to define "forbidden" nodes, i.e., FloydWarshal will never return path leading to such nodes or using such nodes, it would act as edges into / from this node are non-existing.

Parameters:

node -

Returns:

isEdgeOpened

boolean isEdgeOpened(NODE nodeFrom,
                     NODE nodeTo)

Deprecated.

Method defining which "edges" (oriented links between nodes) can be used for the purpose of path-planning. It can be used to "forbid" usage of some edges, that is you can rule out some edges you do not want your agent to be able to travel.

Parameters:

nodeFrom -

nodeTo -

Returns:
