CommandExtensionRegistrar
Constructors
| CommandExtensionRegistrar() |
Properties
| CommandExtensionDefaultStartId |
Provides the start Id of the dynamic Command Group in which the command extension will be placed. This value is used if a CommandExtension does not provide the MenuPlaceholderId value through MEF metadata. |
| CommandSetGuid |
Provide the CommandSet GUID where commands will be placed |
| FilteredImports | (Inherited from ExtensionRegistrarBase<T,TMetadataView>) |
| LazyImports |
List of lazy imports after filtering was applied. (Inherited from ExtensionRegistrarBase<T,TMetadataView>) |
| Logger | |
| MenuService |
Menu command service used to manage command handlers. |
| MetadataFilter |
String-based Metadata Key that determines if a particular Exported Type can be imported or not. The default CanImport implementation filters imports based on this metadata key. The default value of this property is null indicating that no filter will be applied. |
| ServiceProvider | |
| UnfilteredLazyImports |
List of MEF-imported T. (Inherited from ExtensionRegistrar<T,TMetadataView>) |
Methods
| CanImport(Lazy<ICommandExtension,IDictionary<String,Object>>) |
Allow registrars that match the metadatafilter with a key in their metadata to be imported |
| CanImport(Lazy<T,TMetadataView>) |
Determines if for a particular Lazy Import, the underlying exported object should be imported or not. The default implementation allows all imports. (Inherited from ExtensionRegistrarBase<T,TMetadataView>) |
| Compare(Tuple<ICommandExtension,IDictionary<String,Object>>, Tuple<ICommandExtension,IDictionary<String,Object>>) | |
| Compare(Tuple<T,TMetadataView>, Tuple<T,TMetadataView>) |
Compares two imported objects of the same type. (Inherited from ExtensionRegistrarBase<T,TMetadataView>) |
| Initialize(IServiceProvider) |
Assigns a unique commandId to each imported command extension and registers the command with the MenuService. Only commandExtensions whose metadata match the MetadataFilter are registered. |
