# State Machine States Module Documentation
|
||
|
|
|
||
|
|
## 1. Purpose
|
||
|
|
|
||
|
|
This module implements the concrete state classes for a Data Acquisition System (DAS) service state machine within the `DTS.DASLib.Service.StateMachine` namespace. It defines individual state behaviors and state transition logic for the system's operational lifecycle, including hardware discovery, configuration, diagnosis, arming, real-time operation, and data download phases. The states follow a polymorphic design pattern with two class hierarchies: simple states (`DASState`) and state selectors (`DASStateSelector`) that determine the next state transition.

## 2. Public Interface
|
||
|
|
|
||
|
|
### Simple States (inherit from `DASState`)
|
||
|
|
|
||
|
|
#### `Realtime` (public)
|
||
|
|
```csharp
|
||
|
|
public override State State => State.Realtime;
|
||
|
|
```
|
||
|
|
A terminal state representing real-time data acquisition mode. No custom entry behavior is defined in this class.
|
||

|
|
|
||
|
|
### State Selectors (inherit from `DASStateSelector`)
|
||
|
|
|
||
|
|
#### `Configure` (public)
|
||
|
|
```csharp
|
||
|
|
public override State State => State.Configure;
|
||
|
|
public override IDASState StateSelector();
|
||
|
|
public bool AllowApplyConfig();
|
||
|
|
```
|
||
|
|
- **`StateSelector()`**: Returns `States.Instance.ConfigureStart` if `AllowApplyConfig()` returns `true`; otherwise returns `States.Instance.Configure`.
|
||
|
|
- **`AllowApplyConfig()`**: Currently returns `true` unconditionally. Source contains TODO comments indicating future logic for channel resolution validation.
|
||

|
||
|
|
|
||
|
|
#### `ConfigureStart` (public)
|
||
|
|
```csharp
|
||
|
|
public override State State => State.ConfigureStart;
|
||
|
|
public override IDASState StateSelector();
|
||
|
|
public override Action OnEntry { get; }
|
||
|
|
private void ApplyConfig();
|
