java - Custom Edge with jgrapht -



java - Custom Edge with jgrapht -

i want define custom border

public class connection extends defaultweightededge

but when seek utilize super()is possible? should utilize edgefactory when creating graph?

new simpleweightedgraph<sensor, connection>(edgefactory.class);

would sufficient? or should create new class extends edgefactory well?

you not require subclass defaultweightededge create custom edge, next works also. i'm using version 0.9.0 of jgrapht.

class definition :

public class connection { // class implementation // define constructors , methods need }

graph creation :

simpleweightedgraph<sensor, connection> graph; graph = new simpleweightedgraph<sensor, connection>(connection.class);

adding custom border , setting weight :

sensor v1 = // sensor instance sensor v2 = // sensor instance graph.addvertex(v1); graph.addvertex(v2); connection connection = new connection(/* ... */); graph.addedge(v1, v2, connection); graph.setedgeweight(connection, 10.0);

also consider implement equals , hashcode methods of connection class, jgrapht relies on methods since version 0.8.4, see equalsandhashcode article. article provides illustration defaultweightededge subclassed.
