Af:treeTable component: API to return list of expanded nodes?

Question

Hi,
In my UI design, I am using a tree table (af:treeTable component). Does the framework support API to return (at any given time) a list of all expanded nodes?
I realize that I can build logic to 1. return the currently selected node, then 2. query up all of the child nodes of this selected node. However, I'm wondering if, say at a particular instant, multiple nodes have been expanded, and I need a list of all of these nodes for every level in the tree table?
Thanks in advance,
Monica

Hi John,
I am using 11g. From the javadoc, I see that getDisclosedRowKeys() returns "set of disclosed rows for [tree-table] component" and "each entry in the set is a rowKey."
What exactly is the definition of a "disclosed row"? I'm guessing this means any & all rows shown from UI, which would return all rows (including parent nodes of newly expanded nodes)?
Is there a way to return all child nodes (newly displayed rows) of expanded nodes? To clarify, I'm trying to gather rows level by level. If a node has been expanded at level n, I would like to get a new list of nodes at level (n+1).
Thanks,
Monica
