    CodedValueDomainToken Class
    In This Topic
    The Token object to handle schema operations with a ArcGIS.Core.Data.CodedValueDomain.
    Syntax
    public sealed class CodedValueDomainToken : Token 
    Public NotInheritable Class CodedValueDomainToken 
       Inherits Token
    Example
    Creating a CodedValue domain
    public void CreateCodedDomainSnippet(Geodatabase geodatabase)
    {
      // Create a CodedValueDomain description for water pipes
      CodedValueDomainDescription codedValueDomainDescription = new CodedValueDomainDescription("WaterPipeTypes", FieldType.String,
        new SortedList<object, string> { { "C_1", "Copper" }, { "S_2", "Steel" } })
      {
        SplitPolicy = SplitPolicy.Duplicate,
        MergePolicy = MergePolicy.DefaultValue
      };
    
      SchemaBuilder schemaBuilder = new SchemaBuilder(geodatabase);
    
      // Create a coded value domain 
      CodedValueDomainToken codedValueDomainToken = schemaBuilder.Create(codedValueDomainDescription);
      schemaBuilder.Build();
    }
    Adding a Field that uses a domain
    public void AddFieldWithDomainSnippet(Geodatabase geodatabase)
    {
      // Adding a field,'PipeType', which uses the coded value domain to the 'Pipes' FeatureClass
    
      //The FeatureClass to add field
      string featureClassName = "Pipes";
    
      SchemaBuilder schemaBuilder = new SchemaBuilder(geodatabase);
    
      // Create a CodedValueDomain description for water pipes
      CodedValueDomainDescription pipeDomainDescription =
        new CodedValueDomainDescription("WaterPipeTypes", FieldType.String,
        new SortedList<object, string> { { "C_1", "Copper" },
          { "S_2", "Steel" } })
        {
          SplitPolicy = SplitPolicy.Duplicate,
          MergePolicy = MergePolicy.DefaultValue
        };
    
      // Create a coded value domain token
      CodedValueDomainToken codedValueDomainToken = schemaBuilder.Create(pipeDomainDescription);
    
      // Create a new description from domain token
      CodedValueDomainDescription codedValueDomainDescription = new CodedValueDomainDescription(codedValueDomainToken);
    
      // Create a field named as 'PipeType' using a domain description
      FieldDescription domainFieldDescription = new FieldDescription("PipeType", FieldType.String)
      { DomainDescription = codedValueDomainDescription };
    
      //Retrieve existing information for 'Pipes' FeatureClass
      FeatureClassDefinition originalFeatureClassDefinition = geodatabase.GetDefinition<FeatureClassDefinition>(featureClassName);
      FeatureClassDescription originalFeatureClassDescription =
        new FeatureClassDescription(originalFeatureClassDefinition);
    
      // Add domain field on existing fields
      List<FieldDescription> modifiedFieldDescriptions = new List<FieldDescription>(originalFeatureClassDescription.FieldDescriptions) { domainFieldDescription };
    
      // Create a new description with updated fields for 'Pipes' FeatureClass 
      FeatureClassDescription featureClassDescription =
        new FeatureClassDescription(originalFeatureClassDescription.Name, modifiedFieldDescriptions,
                                       originalFeatureClassDescription.ShapeDescription);
    
      // Update the 'Pipes' FeatureClass with domain field
      schemaBuilder.Modify(featureClassDescription);
    
      // Build status
      bool buildStatus = schemaBuilder.Build();
    
      // Build errors
      if (!buildStatus)
      {
        IReadOnlyList<string> errors = schemaBuilder.ErrorMessages;
      }
    }
