Type Parameters:

N - The class of nodes in the graph

E - The class of edges in the graph

All Implemented Interfaces:

public class GraphGeoCanvas<N,E>
extends AbstractGraphDisplay<N,E>
implements GeoDisplay

Implementation of a graph canvas which overlays a geographic display. This class layers a GraphCanvas over a GeoCanvas, and synchronizes their display characteristics. The arrangement algorithm of the GraphCanvas is set to a ProjectionArrangement, and the sizes are synchronized. Other methods implemented by this class are typically delegate methods to the underlying canvases.

Constructor Detail

GraphGeoCanvas

public GraphGeoCanvas(GeoCanvas geoCanvas,
              GraphCanvas<N,E> graphCanvas)

Instantiates a new GraphGeoCanvas.

Parameters:

geoCanvas - the GeoCanvas used to represent the geographic data

graphCanvas - the GraphCanvas used to display the graph.

Method Detail

addLayer

public void addLayer(GeoLayer layer)

Add a layer to the geographic display.

Specified by:

addLayer in interface GeoDisplay

Parameters:

layer - a new geographic layer

getArrangement

public GraphArrangement<N,E> getArrangement()

Gets the arrangement. This method simply returns the ProjectionArrangement

Returns:

the ProjectionArrangement

getEdgeAt

public E getEdgeAt(java.awt.Point point)

Returns the edge located at the pickPoint. This method simply delegates to the internal GraphCanvas.

Specified by:

getEdgeAt in class AbstractGraphDisplay<N,E>

Parameters:

point - the point in the canvas to pick for nodes.

Returns:

the edge at the pickPoint

getGeoBounds

public GeoBounds getGeoBounds()

Get the current geographic bounds

Specified by:

getGeoBounds in interface GeoDisplay

Returns:

the current geographic bounds

getGraph

Get the graph assigned to this display

Specified by:

getGraph in interface GraphDisplay<N,E>

Overrides:

getGraph in class AbstractGraphDisplay<N,E>

Returns:

the current graph

getLayers

public java.util.List<GeoLayer> getLayers()

Get the list of layers. The list is returned in the order that the layers are drawn, so the first layers in the list will be below later ones. This method returns the list of layers in its internal GeoCanvas.

Specified by:

getLayers in interface GeoDisplay

Returns:

the list of layers.

point - the point in the canvas to pick for nodes.

Returns:

the node at the pickPoint

public Projection getProjection()

Get the current projection

Specified by:

getProjection in interface GeoDisplay

Returns:

the current projection

getSelectedEdge
