Remarks

A node can be identified by its key value (in bound mode), content and row handle. Visible nodes (that are not hidden within collapsed nodes) can also be identified by visible indices.

The following images illustrate the difference between row handles and visible indices.

• All nodes are expanded.

  

• One node is collapsed.
