Re: [jgrapht-users] Limited edges number?

[Rushang K. <rus...@ho...>]

I am not sure if this is the solution but does JGraphT provide another identification for an Edge.
 
Say 
 
addEdge(V a, V b)
addEdge(V a, V b, E) where E is the type of edge?
 
addEdge(V a, V b) will add an edge only if there does not exist an edge in the graph already with those objects.
 
Integer a = 42;
Integer b = 50; (add the constructors)
 
addEdge(a, b) will add an edge. 
 
Now if you do
a = 100;
b = 40;
 
addEdge(a,b) it will not add the edge.
 
I would try using the second type of method.
 
String x = ""
 
for total number of edges
{
addEdge(a, b, x)
x += " ";
}
 
I would first see if this fixes the problem. If yes then the problem is that your object references are not changing.
 
Again I do not remember clearly( Long time since I used jgrapht)

Hi Boris,
I'd take a guess that you're using Integer objects to identify nodes, and being caught by Java's curious habit of autoboxing Integers up to 127 only. See this reference: http://bexhuff.com/2006/11/java-1-5-autoboxing-wackyness.
This wouldn't explain why your limit is 50 and not 127, but there may be some arithmetic jiggery-pokery in your code that pushes some important integer into the 127 / 128 range.
My apologies if you're my grandmother and you already know how to suck eggs.

Hi,I've creating an Android project using JgraphT. It works fine except one thing, why can't I add more than 50 edges to WightedGraph like this:
defaultWeightedEdge = (DefaultWeightedEdge) graph.addEdge(fromNode, toNode); ?

Thanks in advance for all replies.Bartek
