How to Generate Code from a UML Model in Visual Studio 2010: Listing 1

Integrating T4 Templates

Shared template isolating the directives, imports and template directives into shared files, which simplifies entry templates. The included file becomes part of the same class as the calling template, and methods in the shared template can be private.

<#@templatedebug="false" hostspecific="true" language="C#" #>
<#@assemblyname="Microsoft.VisualStudio.Uml.Interfaces.dll"#>
<#@assemblyname="Microsoft.VisualStudio.ArchitectureTools.Extensibility.dll"#>
<#@assemblyname="$(SolutionDir)\CommonCompiledDesignTimeSupport.dll" #>
<#@assemblyname="System.Core.dll" #>
<#@importnamespace="System.Linq" #>
<#@importnamespace="System.Collections.Generic" #>
<#@importnamespace="Microsoft.VisualStudio.Uml.Classes" #>
<#@importnamespace="CommonCompiledDesignTimeSupport" #>
<#+

privateModelHelper _helper;

privateModelHelper Helper
{
  get
  {
    if (_helper == null)
    {
      var path = this.Host.ResolvePath("..");
      _helper = newModelHelper(path);
    }
    return _helper;
  }
}

privateIEnumerable<IClass>GetAllClasses()
{	returnHelper.ModelStore.AllInstances<IClass>(); }

privateIEnumerable<IProperty>GetAttributesForClass(IClassclassOfInterest)
{	returnclassOfInterest.OwnedAttributes; }

privateIEnumerable<INamespace>GetNamespacesForClasses()
{ returnHelper.GetNamespacesForClasses();}

publicIEnumerable<IClass>GetClassesForNamespace(INamespacenspace)
{ returnHelper.GetClassesForNamespace(nspace);}

// Etc.
