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 stages in the import process—specifically Options, Preview, and Import. Its purpose is to ensure consistency across the codebase when referencing or routing through these logical steps, likely used in UI navigation, state management, or workflow orchestration components.

2. Public Interface

The module exposes a single nested enum, Steps, defined inside the abstract class GroupImportEnums. Since GroupImportEnums is abstract and contains only the enum, it is not instantiable and serves solely as a namespace-like container.

• GroupImportEnums.Steps
  An enum with three named constants:
  • Steps.Options — Represents the initial configuration step where user-provided options for the import are collected or validated.
  • Steps.Preview — Represents the step where imported data is displayed for user review before final commitment.
  • Steps.Import — Represents the final step where data is persisted or committed.

No methods, properties, or other public members are defined.

3. Invariants

• The Steps enum values are ordered: Options (0), Preview (1), Import (2). This implies a strict sequential progression—no step may be skipped or revisited without explicit reset logic elsewhere.
• The enum is exhaustive for the documented workflow: only these three steps are defined. Any logic assuming additional steps (e.g., Complete, Error) is not supported by this definition.
• The GroupImportEnums class is abstract and contains no instance members; it is not intended for instantiation or inheritance beyond its current use as a container.

4. Dependencies

• No external dependencies: The file imports no namespaces beyond the standard namespace declaration.
• Consumers: Based on naming and structure, this enum is likely consumed by:
  • UI components (e.g., step-by-step wizards or view models)
  • Workflow/state machines managing group import operations
  • Serialization/deserialization logic (e.g., mapping step names to/from strings or integers)
    However, the source file alone does not specify concrete dependents.

5. Gotchas

• No validation or state transition logic: The enum itself does not enforce valid transitions (e.g., Preview → Options is syntactically allowed but may be semantically invalid). Consumers must implement their own transition rules.
• abstract class as namespace container: Using an abstract class solely to nest the enum is unconventional in modern C# (where static class or direct namespace-level enums are preferred). This may indicate legacy design or a pattern to avoid polluting the parent namespace.
• No XML documentation: The source provides no comments, so semantic intent (e.g., whether Preview is read-only or allows edits) is ambiguous.
• No extensibility hooks: Adding new steps requires modifying this enum, which may ripple across consumers. No versioning or extensibility mechanism is evident.
• None identified from source alone.
