GroupTemplate

Documentation: Group Template Interface Module

1. Purpose

This module defines the core interfaces for the Group Template subsystem, which manages reusable template definitions for grouping test channels and associated metadata in the DTS (Device Test System) platform. It provides a layered architecture separating data models (IGroupTemplate, ITestObjectTemplate, IGroupTemplateChannel), view models (IGroupTemplateViewModel, IGroupTemplateListViewModel, ITemplateChannelListViewModel, IGroupTemplateInfoControlViewModel), and view contracts (IGroupTemplateListView, IGroupTemplateExportView, IGroupTemplateImportView, ITemplateChannelListView, IGroupTemplateInfoControlView). These interfaces enable separation of concerns for UI presentation, data binding, and business logic related to template creation, listing, import/export, and channel configuration.

2. Public Interface

Data Model Interfaces

  • IGroupTemplate
    Represents a group template with basic properties: Disabled, Name, Description, Channels, AssociatedGroups, LastModifiedBy, LastModified, SerialNumber. Includes Filter(string term) for client-side filtering.

  • IGroupTemplateChannel
    Represents a channel within a group template. Properties: Custom (read-only), DisplayOrder, NameOfTheChannel, Name (read-only), Required, ISOCode. Includes Filter(string term).

    • GroupTemplateChannelComparer
      Implements IComparer<IGroupTemplateChannel> for sorting. Uses SortField (of type GroupTemplateChannelFields) and Ascending flag. Supports sorting by Required, Name, ISOCode, Custom, and DisplayOrder. Throws ArgumentOutOfRangeException for unsupported sort fields.

  • ITestObjectTemplate
    Represents a test object template (possibly embedded). Properties include TemplateName, TemplateNameOrOriginalTemplateName, Icon, Description, LocalOnly, Version, LastModifiedBy, LastModified, CRC32, TestObject, TestObjectType, TemplateParent, SysBuilt, OriginalTemplateName, Embedded. Includes IsISOMode() method.

View Model Interfaces

  • IGroupTemplateViewModel
    Main view model for group template operations. Properties: ImportView (IGroupTemplateImportView), ExportView (IGroupTemplateExportView). Includes Unset() method (likely for cleanup/disposal).

  • IGroupTemplateListViewModel
    Manages the list view of group templates. Properties: View (IGroupTemplateListView), Templates (array of IGroupTemplate). Methods: GetAllTemplates(bool bIncludeEmbedded, bool bISOMode), Unset(), Sort(object o, bool columnClick), Filter(string term), MouseDoubleClick(int index). Implements IFilterableListView (inherited from IBaseViewModel + IFilterableListView).

  • ITemplateChannelListViewModel
    Manages the channel list for a group template. Properties: View (ITemplateChannelListView). Methods: Unset(), Sort(object o, bool columnClick), Filter(string term), SetAllChannels(IGroupTemplateChannel[] channels), GetAllChannels(), MoveDown(IGroupTemplateChannel channel), MoveUp(IGroupTemplateChannel channel), SetParent(object o).

  • IGroupTemplateInfoControlViewModel
    Manages the info/control view for a selected group template. Properties: View (IGroupTemplateInfoView), SelectedGroupTemplate (IGroupTemplate). Note: IGroupTemplateInfoView is referenced but not defined in this module; its definition is assumed to be in the DataPro.Common.Interface namespace.

View Interface Contracts

  • IGroupTemplateListView
    Marker interface for the group template list view (extends IBaseView).

  • IGroupTemplateExportView
    Marker interface for the group template export view (extends IBaseView).

  • IGroupTemplateImportView
    Marker interface for the group template import view (extends IBaseView).

  • ITemplateChannelListView
    Marker interface for the template channel list view (extends IBaseView).

  • IGroupTemplateInfoControlView
    Marker interface for the group template info/control view (extends IBaseView). Note: This interface is defined in the DataPro.Common.Interface namespace, not DTS.Common.Interface.GroupTemplate.

3. Invariants

  • All view interfaces (IGroupTemplateListView, IGroupTemplateExportView, etc.) are marker interfaces extending IBaseView; they convey no additional contract beyond type identity.
  • View models (IGroupTemplateViewModel, IGroupTemplateListViewModel, etc.) must maintain a valid reference to their corresponding view (via the View property) during active use.
  • IGroupTemplateListViewModel.Templates is expected to be an array of IGroupTemplate instances populated by GetAllTemplates(...).
  • ITemplateChannelListViewModel expects SetAllChannels(...) to be called before GetAllChannels(), MoveUp/Down, or Sort operations to ensure channel data is initialized.
  • IGroupTemplateChannel.Name is read-only and likely derived from NameOfTheChannel or other internal state.
  • ITestObjectTemplate.Embedded and ITestObjectTemplate.TemplateName are related: embedded templates use a GUID as TemplateName, while OriginalTemplateName stores the human-readable name.
  • IGroupTemplate.Filter(string term) and IGroupTemplateChannel.Filter(string term) must implement case-insensitive or substring matching (exact behavior not specified in source).
  • IGroupTemplateInfoControlViewModel requires IGroupTemplateInfoView to be defined elsewhere (in DataPro.Common.Interface).

4. Dependencies

  • Internal Dependencies

    • All interfaces depend on DTS.Common.Base.IBaseView and DTS.Common.Base.IBaseViewModel.
    • IGroupTemplateListViewModel depends on DTS.Common.Interface.Pagination.IFilterableListView.
    • IGroupTemplateChannel depends on DTS.Common.Enums.GroupTemplates.GroupTemplateChannelFields (enum for sort fields).
    • IGroupTemplateInfoControlViewModel depends on DataPro.Common.Interface.IGroupTemplateInfoView (not provided in this module).

  • External Dependencies

    • DataPro.Common.Base namespace (used in IGroupTemplateInfoControlView and IGroupTemplateInfoControlViewModel).
    • System, System.Collections.Generic, System.Linq (implied via IComparer, String.Compare, etc.).

  • Dependents

    • UI layers (e.g., WPF/WinForms views) likely implement the view interfaces.
    • View model implementations (e.g., GroupTemplateListViewModelImpl) depend on these interfaces for DI and testability.
    • Import/export logic likely consumes IGroupTemplateImportView/IGroupTemplateExportView.
    • Channel ordering UI likely consumes ITemplateChannelListViewModel.

5. Gotchas

  • Namespace Inconsistency: IGroupTemplateInfoControlView and IGroupTemplateInfoControlViewModel reside in DataPro.Common.Interface, not DTS.Common.Interface.GroupTemplate, despite being grouped here. This may cause confusion during navigation or refactoring.
  • Missing IGroupTemplateInfoView: Referenced in IGroupTemplateInfoControlViewModel, but not defined in this module. Its contract is unknown.
  • IGroupTemplateChannel.Name vs NameOfTheChannel: Name is read-only, while NameOfTheChannel is read-write. The relationship between them is not documented (e.g., is Name a normalized version?).
  • CRC32 and Version fields: Comments indicate these are “not currently used” or “unsure if this is still used”, suggesting potential dead code or legacy artifacts.
  • TemplateParent and SysBuilt: Comments indicate uncertainty about usage; behavior may be undefined or deprecated.
  • IFilterableListView: Inherited by IGroupTemplateListViewModel, but its contract (e.g., FilterTerm property, OnFilterChanged event) is not visible here.
  • Unset() method: Used across multiple view models; likely for cleanup, but semantics (e.g., nulling View, releasing resources) are not specified.
  • MouseDoubleClick(int index): Signature implies index-based selection, but no context (e.g., which item, event args) is provided—potential source of off-by-one or stale-index bugs.
  • No generic constraints: View models accept object for Sort(object o, bool columnClick) and SetParent(object o), risking runtime type errors if callers pass unexpected types.
