# StateMachine Module Documentation

## 1. Purpose

This module implements a state machine for managing system operational states within the DTS.DASLib.Service namespace. It provides state transition logic for a data acquisition system (DAS) that progresses through hardware discovery, configuration, diagnostics, download, arming, and realtime operation phases. Each state class encapsulates its own transition logic via a `StateSelector()` method that determines the next appropriate state based on runtime status and parameter conditions.

## 2. Public Interface

### State Enum
An enumeration defining all possible system states. Observed values include:
- `State.HardwareDiscoveryStart`
- `State.HardwareDiscovery`
- `State.Configure`
- `State.ConfigureStart`
- `State.Download`
- `State.Arm`
- `State.Diagnose`
- `State.RealtimeStart`
- `State.Realtime`

### Realtime Class
**Properties:**
- `State` — Returns `State.Realtime`

**Methods:**
- None observed in tests (terminal state).

---

### Configure Class
**Methods:**
- `StateSelector()` — Returns a `dasState` object with `State.ConfigureStart
