Microsoft Extensibility Framework (MEF) is used to dynamically load Plugins into the UBIK Kernel.

Basic Prerequisites

If you want to create a Plugin which can be loaded in UBIK you have to refer to System.ComponentModel.Composition.

UBIK Injection Managemnt provides access to all the basic features used by the Kernel to identifiy and categorize the available Plugins. This management is provided by a library called UBIK.Injection. You have to refer to this library as well.

References:

  • System.ComponentModel.Composition
  • UBIK.Injection


Interface UBIK.Injection.IUbikPlugin

Your plugin must implement the Ubik Plugin Interface. To register your plugin for MEF composition by defining the export contract via an Attribute.

    [Export(typeof(UBIK.Injection.IUbikPlugin))]
    public class myPlugIn : UBIK.Injection.IUbikPlugin
    {
    }


MetaData

Ubik needs some Meta Information to manage plugins correctly. The available MetaInformation are defined by the interface UBIK.Injection.IUbikInjectionMetaData

Mandatory information

Name Type Description
ID string Unique ID of the Plugin
Type System.Type Systemtype of the Plugin. Used for filtering the Plugins during loading.


Optional information

Name Type Description
Name string Name of the plugin (for UI Presentation)
Description string Name of the plugin (for UI Presentation)
Version int Version of the plugin. As there are more plugins with the same ID, only the plugin with the highest Version is available.
TargetApplication PluginTargetApplication Possibility to limit the plugin for a single type of application.
MinimumKernelVersion string Minimum required Kernel version: Format x.x.x.x
MinimumDatabaseVersion string Minimum required Database version: Format x.x.x.x


Example:

    [Export(typeof(UBIK.Injection.IUbikPlugin))]
    [ExportMetadata("ID", "23B72354-A26F-449E-A7DA-F874B4167248")]
    [ExportMetadata("Type", typeof(UBIK.Injection.IUbikPlugin))]
    [ExportMetadata("Name", "my Plugin")]
    [ExportMetadata("Description", "does fancy things in version 2.4")]
    [ExportMetadata("Version", 3)]
    [ExportMetadata("MinimumKernelVersion", "2.4.0.0")]
    [ExportMetadata("MinimumDatabaseVersion", "2.4.0.0")]
    public class myPlugIn : UBIK.Injection.IUbikPlugin
    {

    }
