# Enums

## 1. Purpose  
This module defines core licensing-related enumerations used throughout the DataPro system. Specifically, it declares the `LicenseType` enum, which categorizes different software license tiers available in the product. Its role is to provide a standardized, type-safe representation of license types across licensing validation, feature gating, and configuration logic in the broader codebase.

## 2. Public Interface  
The only public type exposed is the `LicenseType` enum, nested inside the `DataProLicensingEnums` class.

- **`DataProLicensingEnums.LicenseType`**  
  - **Definition**: `public enum LicenseType`  
  - **Values**:  
    - `Standard = 0`  
    - `Enterprise = 1`  
    - `EnterpriseSite = 2`  
    - `TSRAir = 3`  
    - `StandardSite = 4`  
  - **Behavior**: Represents discrete license tiers. Values are explicitly assigned integer constants (0–4). The `StandardSite` value was added in response to feature request FB 30628.

## 3. Invariants  
- The `LicenseType` enum contains exactly five defined values; no others are declared in this file.  
- Each enum value maps to a unique underlying integer (0 through 4), with no duplicates.  
- The enum is *not* marked with `[Flags]`, implying values are mutually exclusive and not combinable via bitwise operations.  
- The enum is declared as `public`, but the containing class `DataProLicensingEnums` is also `public` and non-static—however, it serves only as a namespace-like container for the enum (a common C# pattern for grouping related enums).

## 4. Dependencies  
- **Dependencies *of* this module**:  
  - `System`, `System.Collections.Generic`, `System.Linq`, `System.Text`, `System.Threading.Tasks` (standard .NET namespaces).  
- **Dependencies *on* this module**:  
  - Not inferable from this file alone. However, given the namespace `DTS.Common.Licensing`, it is highly likely that other modules in the `DTS.Common.*` assembly (e.g., licensing validation, feature management, or UI components) depend on this enum.  

## 5. Gotchas  
- The class `DataProLicensingEnums` is non-static and contains only an enum—this is unusual and may cause confusion (e.g., developers might instantiate it unnecessarily). It likely exists for historical or organizational reasons.  
- The comment `//FB 30628 Added StandardSite license type` indicates a feature request reference; developers should consult external tracking (e.g., Jira, Azure DevOps) for full context if needed.  
- No validation or conversion helpers (e.g., `TryParse`, `IsValid`) are defined in this file—consumers must implement their own validation if required.  
- No documentation comments (XML doc comments) are present on the enum or its members; developers must infer semantics from names and comments alone.  
- None identified from source alone.
