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.
