class wtGraph

extends wtObject

A container for G=(V,E) vertices and their corresponding edges.
Defined in wt_vector.js

Constructor Detail

wtGraph

wtGraph(<wtCanvas> parentCanvas)

Constructs a G=(V,E) graph.

Parameters:
parentCanvas - The container canvas.

addVertex

Object addVertex(<wtGraphVertex> vertex)

Adds a vertex to this graph.

Parameters:
vertex - The vertex to be added.

getCanvas

wtCanvas getCanvas()

Tells the container canvas of this graph.

Returns:
The container canvas.

getVertices

Object getVertices()

Tells the vertices contained in this graph.

Returns:
All graph vertices in an id:vertex dictionary.

linkFromMouse

Object linkFromMouse(<wtGraphVertex> sourceVertex, <Class> edgeClass)

Generates an edge whose source is fixed to be one vertex and let the user select the terminal vertex from the same graph with his mouse.

Parameters:
sourceVertex - The source vertex.
edgeClass - (Optional) The edge class used for generating the new graph edge.

linkToMouse

Object linkToMouse(termVertex, <Class> edgeClass)

Generates an edge whose terminal is fixed to be one vertex and let the user select the source vertex from the same graph with his mouse.

Parameters:
edgeClass - (Optional) The edge class used for generating the new graph edge.
terminalVertex - The terminal vertex.

linkVertices

Object linkVertices(<wtGraphVertex> sourceVertex, <wtGraphVertex> terminalVertex, <Class> edgeClass)

Links two vertices with an edge from an optionally specified edge class.

Parameters:
sourceVertex - The source vertex.
terminalVertex - The terminal vertex.
edgeClass - (Optional) The edge class used for generating the new graph edge.

removeVertex

void removeVertex(<wtGraphVertex> vertex)

Removes a vertex from this graph.

Parameters:
vertex - The vertex to be removed.

unlinkVertices

void unlinkVertices(<wtGraphVertex> sourceVertex, <wtGraphVertex> terminalVertex)

Unlinks two vertices.

Parameters:
sourceVertex - The source vertex.
terminalVertex - The terminal vertex.
