Example 6 with NodeDiff

use of org.apache.cayenne.graph.NodeDiff in project cayenne by apache.

the class DeleteRulesIT method assertJoinNotDeleted.

private void assertJoinNotDeleted(DeleteRuleFlatA a, DeleteRuleFlatB b) {
    ObjectDiff changes = context.getObjectStore().changes.get(a.getObjectId());
    if (changes != null) {
        Collection<NodeDiff> diffs = new ArrayList<NodeDiff>();
        changes.appendDiffs(diffs);
        Iterator<?> it = diffs.iterator();
        while (it.hasNext()) {
            Object diff = it.next();
            if (diff instanceof ArcOperation) {
                ArcOperation arcDelete = (ArcOperation) diff;
                if (arcDelete.getNodeId().equals(a.getObjectId()) && arcDelete.getTargetNodeId().equals(b.getObjectId()) && arcDelete.getArcId().equals(DeleteRuleFlatA.FLAT_B.getName()) && !arcDelete.isDelete()) {
                    fail("Join was  deleted for flattened relationship");
                }
            }
        }
    }
}

Example 7 with NodeDiff

    NodeDiff diff = new ArcOperation(nodeId, targetNodeId, arcId.toString(), true);
    if (lifecycleEventInducedChanges != null) {
