Method Detail

stopTraversal

public void stopTraversal()

Once this is called, all visit methods will return false. If the current node's children are being visited, all remaining top-level children of the node will be visited (without visiting their children), and then tree traversal halts.

If the traversal should be halted immediately without visiting any further nodes, the visitor can throw a NNodeVisitor.StopIterationException.
