Method Detail

getGraph

Graph<N,E> getGraph()

Get the graph assigned to this display

Returns:

the current graph

getSelectedEdge

E getSelectedEdge()

Gets the current selected edge.

Returns:

the current selected edge

getSelectedNode

N getSelectedNode()

Gets the current selected node.

Returns:

the current selected node, or null if no node is selected

selectEdge

void selectEdge(E edge)

Programatically sets the currently selected edge

Parameters:

edge - the currently selected edge, or null if no edge is selected

selectNode

void selectNode(N node)

Programatically sets the currently selected node

Parameters:

node - the node to be selected

setGraph

void setGraph(Graph<N,E> graph)

Set the graph to be displayed

Parameters:

graph - the graph to be displayed

updateGraph

void updateGraph()

Update the currently displayed graph. This call should be invoked when the graph's contents change, such as when new nodes are added. Implementations should maintain selection status and arrangement where possible.
