Class NodeData<T>

java.lang.Object

ch.sahits.game.openpatrician.engine.sea.model.NodeData<T>

Type Parameters:

T -

public final class NodeData<T>
extends Object

NodeData stores all information of the node needed by the AStar algorithm. This information includes the value of g, h, and f. However, the value of all 3 variables are dependent on source and destination, thus obtains at runtime.
