I have a tree of nodes, something like this in pseudocode:
class Node
ArrayList kidnodes
Node parent
So - each node has kids and a parent.
I find myself wanting to foreach over the tree from code that is not
within a Node.
Right now, I'm doing this kind of thing:
class Node
...
public void walk( somelist)
foreach(kid in kidnodes)
somelist.add (kid) //visit.
walk( somelist )
Then, in some other object:
var list = somelist
somenode.walk(l)
//now i can foreach through "list"
Is there some way I can do:
somenode = rootnode; //say
foreach( node in somenode)
visit(node)
so that it visits the nodes like walk does?
