Iterable getDescendants() within CategoryGraph constructor causes endless loop #10

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

Required is access to a running mysql database with a converted version of 
wikipedia.
Connecting to the database is done as shown in tutorials.

Following excerpt of code causes a endless loop.

String firstDomain = "Photosynthesis";
Category firstCat = wiki.getCategory(firstDomain);
CategoryGraph catGraph =
       new CategoryGraph(wiki, firstCat.getDescendants());
System.out.println(catGraph.getNumberOfNodes());

What is the expected output? What do you see instead?

As Photosynthesis has currently about 7 subcategories. I expect to get the 
number 7 in a reasonable time.

Instead I get no results and the program runs endlessly.

What version of the product are you using? On what operating system?
Current version on Open Suse 11.2
