示例1: clear
// Clear environment.
void clear(void)
{
tree_t::iter it;
node *n;
it.start_iter_least(tree);
// A useful property of this data structure is the ability to do a
// "death march" through it. Once the iterator (forward or backward)
// has stepped past a node, the node is not accessed again (assuming
// you don't reverse the direction of iteration). If you are doing
// a final iteration in order to destroy the tree, you can release
// heap memory or other resources allocated by the tree node once the
// iterator has stepped past it. If you plan to use the AVL tree
// instance again after completing this final iteration, you must
// make it empty (set the root to the null value).
for (n = *it; n; n = *it)
{
// Step iterator past node n.
it++;
// Release node n's resources.
delete [] n->name;
delete [] n->value;
delete n;
}
// Make the tree empty by setting root to null value.
tree.purge();
