# Documentation: DTS.Common.Validators

## 1. Purpose

This module provides WPF `ValidationRule` implementations for validating user input in the DTS application's UI layer. It contains three specialized validators: `SensitivityValidator` for ensuring numeric sensitivity values are non-zero, `UARTBAUDRateValidator` for validating UART baud rate configuration values against defined min/max bounds, and `CANArbBaseBitrateValidator` for validating CAN arbitration/base bitrate values. These validators are designed for use in WPF data binding scenarios where input validation is required before accepting user-provided string values.

## 2. Public Interface

### `SensitivityValidator`
**Inherits from:** `ValidationRule`

| Method | Signature | Description |
|--------|-----------|-------------|
| `Validate` | `public override ValidationResult Validate(object value, CultureInfo cultureInfo)` | Validates that the input is a parseable `double` and is not equal to zero. Returns `ValidationResult(false, StringResources.InvalidFormat)` if the value cannot be parsed as a double or is not a string. Returns `ValidationResult(false, StringResources.SensitivityCanNotBeZero)` if the parsed value equals `0D`. Returns `ValidationResult(true, null)` for valid non-zero numeric input. |

---

### `UARTBAUDRateValidator`
**Inherits from:** `ValidationRule`

| Method | Signature | Description |
|--------|-----------|-------------|
| `Validate` | `public override ValidationResult Validate(object value, CultureInfo cultureInfo)` | Validates that the input is a parseable `long` within the UART baud rate range. Returns `ValidationResult(false, StringResources.InvalidFormat)` if the value cannot be parsed as a long or is not a string. Returns `ValidationResult(false, ...)` with min/max error messages if the value falls outside `Constant.EmbeddedSensors.BAUD_RATE_MIN` or `Constant.EmbeddedSensors.BAUD_RATE_MAX`. Returns `ValidationResult(true, null)` for valid input within bounds. |
