**Header:** `ClikaRT/graph/node.h`  
**Template:** `template <``class T``>`

One `T` per node (a weight, a score, a depth), iterating in the order the entries were added. Keyed by [`Node`](./Node.md) views, which compare by name, so an entry still finds its node after the graph is edited.

## Types

## Member functions

### operator\[\]() {#operator-subscript}

<div class="api-signature">

`T&` **`operator[]`**(`const` [`Node`](./Node.md)`&` `node`)

</div>

The entry for `node`, added as a value-initialized `T` when absent.
