# NOM — Number of Methods

> Number of functions and closures declared in a file, trait, or class.

**NOM** (Number of Methods) counts how many functions and closures live inside a unit (file, trait,
class, or module).

## What mehen emits

| Key                                              | Type  | Description                                    |
| ------------------------------------------------ | ----- | ---------------------------------------------- |
| `nom`                                            | int   | Total methods (named functions + closures).    |
| `nom.functions`                                  | int   | Number of named functions.                     |
| `nom.closures`                                   | int   | Number of closures/lambdas.                    |
| `nom.functions_min` / `_max` / `_average`        | —     | Aggregates across child spaces.                |
| `nom.closures_min` / `_max` / `_average`         | —     | Aggregates across child spaces.                |
| `nom.average_functions` / `nom.average_closures` | float | Means per child space.                         |
| `nom.total_functions` / `nom.total_closures`     | int   | Aliases of `nom.functions` and `nom.closures`. |

## How to read it

| `nom` | Interpretation                                                               |
| ----- | ---------------------------------------------------------------------------- |
| 1–10  | Small file/class; usually fine.                                              |
| 11–25 | Medium; expected in most app-layer code.                                     |
| 26+   | Likely a god-class candidate; pair with [WMC](/metrics/code/wmc) to confirm. |

The split between `nom.functions` and `nom.closures` is informative. A file with 5 named functions and
50 closures is usually a callback-heavy piece (e.g., an event-driven module).
