## TreeMap 0.1
[![Elixir CI](https://github.com/iboard/tree_map/actions/workflows/elixir.yml/badge.svg)](https://github.com/iboard/tree_map/actions/workflows/elixir.yml)
A module to maintain a tree of the structure
```elixir
%TreeMap{ key: ..., value: ..., children: [%TreeMap{},...]}
```
and functions to traverse such a tree.
### Examples
```elixir
root =
TreeMap.new("1", "Root")
|> TreeMap.add_child("1.1", "Sub One", [TreeMap.new("1.1.1", "SomeSubSub")])
|> TreeMap.add_child("1.2", "Sub Two", [TreeMap.new("1.2.1", "Some other SubSub")])
expected = ["1", "1.1", "1.1.1", "1.2", "1.2.1"]
received =
TreeMap.transduce(root, [], fn a, x -> a ++ [x] end, fn n, acc -> [n | acc] end)
|> Enum.map(& &1.key)
assert expected == received
```
### RootServer
`TreeMap.RootServer` is a `DynamicSupervisor` that can be used to maintain a tree of `TreeMap` nodes.
#### Examples
iex> TreeMap.list_roots()
[%Node{}, ...]
iex> TreeMap.find("key")
%Node{}
iex> TreeMap.drop_all()
[:ok, ...]
## Installation
[Available in Hex](https://hex.pm/packages/tree_map), the package can be
installed by adding `tree_map` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:tree_map, "~> 0.1.0"}
]
end
```
