10.6. Implement Token Value Accessor Set

Follow these step to create the item model and converter for token value accessor set.

1. In Visual Studio, add the following class:

   using Sitecore.Services.Core.Model;
   
   namespace DataExchange.Providers.RESTful.Models.ItemModels.DataAccess.ValueAccessorsSets
   {
       public class TokenValueAccessorSetsItemModel : ItemModel
       {
       }
   }
   

2. Add the following class:

   using System;
   using System.Collections.Generic;
   using Sitecore.DataExchange;
   using Sitecore.DataExchange.Converters.DataAccess.ValueAccessors;
   using Sitecore.DataExchange.Repositories;
   using Sitecore.Services.Core.Model;
   using DataExchange.Providers.RESTful.Models.ItemModels;
   using DataExchange.Providers.RESTful.Models.ItemModels.DataAccess.ValueAccessors;
   
   namespace DataExchange.Providers.RESTful.Converters.DataAccess.ValueAccessorsSets
   {
       public class TokenValueAccessorSetsConverter : ChildBasedValueAccessorSetConverter, IConverter<ItemModel, ICollection<string>>
       {
           public TokenValueAccessorSetsConverter(IItemModelRepository repository) : base(repository)
           {
               this.SupportedTemplateIds.Add(Templates.TokenValueAccessorSet.TemplateId);
           }
   
           ConvertResult<ICollection<string>> IConverter<ItemModel, ICollection<string>>.Convert(ItemModel source)
           {
               if (!base.IsSupportedItem(source))
                   return ConvertResult<ICollection<string>>.NegativeResult(this.FormatMessageForNegativeResult(source, "The source item is not supported by this converter.", Array.Empty<string>()));
   
               var stringSet = new HashSet<string>();
   
               var childItemModels = this.GetChildItemModels(source);
               if (childItemModels != null)
               {
                   foreach (var itemModel in childItemModels)
                   {
                       var path = this.GetStringValue(itemModel, TokenValueAccessorItemModel.PathExpression);
                       if (!string.IsNullOrWhiteSpace(path) && this.GetBoolValue(itemModel, CommonItemModel.Enabled))
                           stringSet.Add(path);
                   }
               }
   
               return ConvertResult<ICollection<string>>.PositiveResult(stringSet);
           }
       }
   }
   

   Important

   v1.4.1 or earlier: The Sitecore.DataExchange.ConvertResult class was introduced in Data Exchange Framework 2.0, and the Converter classes were updated to use the ConvertResult class to track positive and negative results.

   using System.Collections.Generic;
   using Sitecore.DataExchange;
   using Sitecore.DataExchange.Converters.DataAccess.ValueAccessors;
   using Sitecore.DataExchange.Models.ItemModels.Common;
   using Sitecore.DataExchange.Repositories;
   using Sitecore.Services.Core.Model;
   using DataExchange.Providers.RESTful.Models.ItemModels.DataAccess.ValueAccessors;
   
   namespace DataExchange.Providers.RESTful.Converters.DataAccess.ValueAccessorsSets
   {
       public class TokenValueAccessorSetsConverter : ChildBasedValueAccessorSetConverter, IConverter<ItemModel, ICollection<string>>
       {
           public TokenValueAccessorSetsConverter(IItemModelRepository repository) : base(repository)
           {
               this.SupportedTemplateIds.Add(Templates.TokenValueAccessorSet.TemplateId);
           }
   
           ICollection<string> IConverter<ItemModel, ICollection<string>>.Convert(ItemModel source)
           {
               var stringSet = new HashSet<string>();
   
               if (this.CanConvert(source))
               {
                   var childItemModels = this.GetChildItemModels(source);
                   if (childItemModels != null)
                   {
                       foreach (var itemModel in childItemModels)
                       {
                           var path = this.GetStringValue(itemModel, TokenValueAccessorItemModel.PathExpression);
                           if (!string.IsNullOrWhiteSpace(path) && this.GetBoolValue(itemModel, EnableableItemModel.Enabled))
                               stringSet.Add(path);
                       }
                   }
               }
   
               return stringSet;
           }
       }
   }
