# Documentation: DTS.Common.Events.Sensors

## 1. Purpose

This module defines event types for the Prism pub/sub event system, specifically for sensor-related state changes. It provides three event classes that enable loosely-coupled communication between components: two for calibration behavior setting changes (`CalibrationBehaviorSettingChangedEvent` and `ExportCalibrationBehaviorSettingChangedEvent`), and one for sensor filter type changes (`SensorFilterTypeChangedEvent`). These events facilitate notification when sensor calibration behaviors or filter configurations are modified, allowing subscribers to react without direct coupling to the event publishers.

## 2. Public Interface

### `CalibrationBehaviorSettingChangedEvent`
**Signature:**
```csharp
public class CalibrationBehaviorSettingChangedEvent : PubSubEvent<DTS.Common.Enums.Sensors.CalibrationBehaviors>
```
A pub/sub event that carries a `CalibrationBehaviors` enum value as its payload. Used to notify subscribers when a calibration behavior setting has changed.

---

### `ExportCalibrationBehaviorSettingChangedEvent`
**Signature:**
```csharp
public class ExportCalibrationBehaviorSettingChangedEvent : PubSubEvent<DTS.Common.Enums.Sensors.CalibrationBehaviors>
```
A pub/sub event that carries a `CalibrationBehaviors` enum value as its payload. Used to notify subscribers when an export-related calibration behavior setting has changed. Distinct from `CalibrationBehaviorSettingChangedEvent` to allow separate subscription channels.

---

### `SensorFilterTypeChangedEvent`
**Signature:**
```csharp
public class SensorFilterTypeChangedEvent : PubSubEvent<SensorFilterTypeChangedEventArgs>
```
A pub/sub event that carries `SensorFilterTypeChangedEventArgs` as its payload. Used to notify subscribers that a sensor filter or ISO code filter field has changed.

---

### `SensorFilterTypeChangedEventArgs`
**Signature:**
```csharp
public class SensorFilterTypeChangedEventArgs
```

**Properties:**
| Property | Type | Access |
|----------|------|--------|
| `ISOCodeChar` | `char` | `public get; private set` |
| `EventType` | `EventTypes` | `public get; private set` |
| `FilterClass` | `FilterClassType` | `public get; private set` |
| `Calibration` | `ISensorCalibration` | `public get; private set` |
| `Sensor` | `ISensorData` | `public get; private set` |
| `UseISOCodeFilterMapping` | `bool` | `public get; private set` |
| `UseZeroForUnfiltered` | `bool` | `public get; private set` |

**Nested Enum:**
