[JBoss JIRA] Created: (DNA-407) ReadBranchRequest.iterator() returns too many nodes

ReadBranchRequest.iterator() returns too many nodes
---------------------------------------------------
Key: DNA-407
URL: https://jira.jboss.org/jira/browse/DNA-407
Project: DNA
Issue Type: Bug
Components: Connectors, Graph
Affects Versions: 0.4
Reporter: Randall Hauch
Assignee: Randall Hauch
Fix For: 0.5
The ReadBranchRequest.iterator() method returns an iterator that walks (in pre-order traversal) the nodes that were set as results on the request. The iterator is to walk all the nodes in the branch and should not include the children of the bottom nodes in the branch. However, this is what the iterator is currently doing.
For example, consider a graph in a repository:
A
+- B
| +- C
+- D
If the ReadRequestBranch is submitted with a path of '/A' and maximum depth of 2, then the branch should include all the properties and children for nodes A, B and D. Node C should not be included in the branch because it is below the maximum depth. The current implementation of the iterator is also returning node C; not only is this wrong, but it also generates an NPE when iterating.
