Method Detail

init

@PostConstruct
private void init()

initGraph

public void initGraph(HeuristicGraphInitialisationComplete event)

createGraph

void createGraph()

addDestinationPoint

public void addDestinationPoint(javafx.geometry.Point2D newPoint,
                                boolean isCity)

Add a new destination Node to the graph. The new point is added to the heuristic as target and to the graph together with edges to its nearest neighbors and they back to the new node.

Parameters:

newPoint - new location to add to the graph

isCity - flag indicating if the new location is a city, which means the coordinates may not be located in the sea area.

addDestinationPointInternal

void addDestinationPointInternal(javafx.geometry.Point2D newPoint,
                                 boolean isCity)

addSourcePointInternal

void addSourcePointInternal(javafx.geometry.Point2D source,
                            boolean isCity)

calculateWeight

protected double calculateWeight(javafx.geometry.Point2D from,
                                 javafx.geometry.Point2D to)

Description copied from class: BaseGraphCalulationService

Calculate the weight between two nodes.

Specified by:

calculateWeight in class BaseGraphCalulationService

Parameters:

from - source node

to - destination node

Returns:

weight of the edge from node from to to

addEdges

private void addEdges(javafx.geometry.Point2D from,
                      javafx.geometry.Point2D to,
                      boolean isCity,
                      boolean initial)

initImage

void initImage()
        throws IOException

Throws:

IOException

getGraph

public GraphAStar<javafx.geometry.Point2D> getGraph()
