[Neo4j] Attributes or Relationship Check During Traversal

2010-08-01 Thread Alex D'Amour
Hello all, I have a question regarding traversals over a large graph when that traversal depends on a discretely valued attribute of the nodes being traversed. As a small example, the nodes in my graph can have 2 states -- on and off. I'd like to traverse over paths that only consist of active

Hello all, Is there an easy way to create an iterator over all relations stored in a database? There's database.getAllNodes(). Why isn't there a getAllRelationships() method? There appears to have been one in the past, but it looks like it's protected now? Is there a specific reason why this
