# Groups
|
||
|
|
|
||
|
|
## 1. Purpose
|
||
|
|
This module defines a strongly-typed enumeration for the sequential steps involved in a group import workflow. It resides in the `DTS.Common.Enums.Groups` namespace and serves as a centralized, type-safe reference for the distinct phases—`Options`, `Preview`, and `Import`—that constitute the group import process. Its role is to ensure consistency across the codebase when referencing or routing through these steps, particularly in UI navigation, state management, or workflow orchestration logic.
|
||
|
|
|
||
|
|
## 2. Public Interface
|
||
|
|
The module exposes a single nested `enum` type:
|
||
|
|
|
||
|
|
- **`GroupImportEnums.Steps`**
|
||
|
|
An `enum` with three named constants:
|
||
|
|
- `Options`: Represents the initial step where user-provided configuration or selection options are collected.
|
||
|
|
- `Preview`: Represents the step where imported data is displayed for review before final commitment.
|
||
|
|
- `Import`: Represents the final step where the data is committed or persisted.
|
||
|
|
|
||
|
|
All values are implicitly of type `int`, with default underlying values (`Options = 0`, `Preview = 1`, `Import = 2`), though the source does not explicitly declare numeric values.
|
||
|
|
|
||
|
|
## 3. Invariants
|
||
|
|
- The sequence of steps is strictly ordered: `Options` → `Preview` → `Import`.
|
||
|
|
- No other steps are defined beyond these three; any extension requires modifying this enum.
|
||
|
|
- The enum is declared as `public abstract class GroupImportEnums` containing the nested `enum Steps`, but since `GroupImportEnums` is abstract and contains no instance members, it serves solely as a namespace-like container for `Steps`. (Note: This is a common C# pattern for grouping enums, though the class itself is never instantiated.)
|
||
|
|
|
||
|
|
## 4. Dependencies
|
||
|
|
- **Internal**: Depends on the .NET runtime (`System` namespace implicitly, via `enum`).
|
||
|
|
- **External usage**: Inferred to be consumed by modules handling group import workflows (e.g., UI layers, import services), though no direct dependencies are visible in this file.
|
||
|
|
- **No external dependencies** are declared in this source file (no `using` directives present).
|
||
|
|
|
||
|
|
## 5. Gotchas
|
||
|
|
- The outer class `GroupImportEnums` is `abstract` but serves no functional purpose beyond namespacing the `Steps` enum; it cannot be instantiated and contains no static members. This may confuse developers expecting utility methods or constants.
|
||
|
|
- The enum values are not explicitly assigned numeric values, relying on default sequential ordering. While stable in practice, this could break if reordering or inserting intermediate steps without updating consumers that assume specific numeric values.
|
||
|
|
- No validation or conversion helpers (e.g., `TryParse`, `GetDescription`) are provided in this file—any such functionality must exist elsewhere.
|
||
|
|
- None identified from source alone.
