Question

I was wondering how to save a Binary Tree that I have previously created.
Does anyone know how to do it?
Thank you so much.

PD: Here there is a link about how to implement a binary tree, I am using this pice od code:

One easy solution:
– extend the current class to have a load and save method
– add a unique id to each node
– implement to do a top down parsing and save each node to a xml with a structure like that

<node id="mynicelycrafteduniqueid">
    <data>...</data>
    <leftChild>childuniqueId</leftChild>
    <rightChild/> <!-- no right child -->
</node>

You’re done (if data is easily serialized at least), first node is your tree root.

don’t forget fertilizer and your tree will be reborn even more beautiful
