Get tree

19.0.0 released Nov 08, 2023

Get tree

Purpose: Get information about tree.

get-tree <tree> \
    ( count | hops ) \
    to [ define ] <result>

get-tree provides information about <tree> (created by new-tree), which is stored in <result> (in "to" clause):

"count" clause provides the number of keys (i.e. nodes) in the tree.
"hops" clause provides the number of nodes accessed to find a key in the last tree statement executed prior to get-tree. Note that "hops" is available only in debug Vely build (see installing from source); otherwise it is always zero.

<result> can be created with optional "define".

Examples
Get the number of nodes (keys) in a tree:
```
new-tree mytree
...
get-tree mytree count to define c
```
