Rick Hillegas commented on DERBY-3946:
--------------------------------------
Hi Ciu,
Some responses follow:
1) The printing is triggered by the call to QueryTreeNode.treePrint(). That
method immediately defers its work to QueryTreeNode.printSubNodes(), which
recurses through the nodes, printing as it goes.
2) The *s are expanded by ResultColumnList.expandAllsAndNameColumns().
Hope this helps,
-Rick
