Thanx to both of you. Yes, I can just check whether the label exists

what is assigned when the subscriber node is created.
To assign a temporary value (or a value representing
One other option is to have a set of nodes, each of which represents a
component. You can create a relationships of type OWNS (or whatever) to
each of the nodes of a given component. This makes component lookup rather
simple (just grab the node that represents the component, then traverse all
of
The union find algorithm would be appropriate for labeling connected
components as you build the graph.

Hi All
I'm trying to label all connected components in a graph - i.e. all
nodes that are connected will have a common componentID property
set. I'm using the Traverser to do this. For each node in the graph
(unless it is already labelled, which I track by inserting the node ID
in a list), the
The first obvious thing is that labelled.contains(currentNode.getId()) is
going to take more time as your dataset grows, since it's a linear search
for the element in an ArrayList. A HashSet would be a much more appropriate
data structure for your application.
The other thing that comes to mind
Thanx to both of you. Yes, I can just check whether the label exists

BTW - is it ever possible to label the components while creating the
graph? I can't think of any way of
