Hi Michael
Doesn't handle iterables (yet) but should be quite easy to add in. What
purpose did you have behind longs?
I've just committed a few new methods allowing the Neo4jNamespace returned
from a loadIntoNeo4j call to be used to retrieve new entities by name (or a
map of such). The new methods are:
public Node getPreexistingNode(String name)
public Map<String, Node> getPreexistingNodes(String... names)
public Node getNewlyCreatedNode(String name)
public Map<String, Node> getNewlyCreatedNodes(String... names)
public Relationship getPreexistingRelationship(String name)
public Map<String, Relationship> getPreexistingRelationships(String...
names)
public Relationship getNewlyCreatedRelationship(String name)
public Map<String, Relationship> getNewlyCreatedRelationships(String...
names)
One of the tests in GraphDescriptionTest illustrates simple usage, thus:
Neo4jNamespace ns = GEOFFLoader.loadIntoNeo4j(reader, db, hooks);
Node nodeFoo = ns.getNewlyCreatedNode("foo");
Node nodeBar = ns.getNewlyCreatedNode("bar");
Hope this helps - I'll have a play with iterables next.
Cheers
Nige
