Is there a way to retrieve the tree structure for further modification?

[cloudray8580]

Hi, I'm not sure if it's able to retrieve the tree structure for further modification.
For example, I may want to build a rtree using the current wrapper, then
add an extra aggregate count attribute in each node (from leaf to root).
But is there any way to retrieve the internal nodes (which maintain the tree structure)?

In addition, when I want to control the leaf size using leaf_capacity and fill_factor, why every leaf node turn out to be the minimum size (i.e., 5000 here)? Did I miss anything?

p = index.Property()
p.leaf_capacity = 10000
p.fill_factor = 0.5
p.overwrite = True
idx = index.Index(DatasetGenerator(dataset),properties = p)
leaves = idx.leaves()
