Create UBIK Plugin
UBIK® Plugins are dynamically loaded into the UBIK® Kernel via the Injection Management using the Microsoft Extensibility Framework (MEF).
Contents
Basic Prerequisites
If you want to create a plugin which can be loaded into UBIK® you have to include references to
- System.ComponentModel.Composition
- UBIK.Injection
UBIK® Injection Management 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.
Interface: IUbikPlugin
The plugin must implement the UBIK.Injection.IUbikPlugin interface and has to be registered for MEF composition by defining the export contract via an attribute.
[Export(typeof(UBIK.Injection.IUbikPlugin))]
public class TestPlugin : UBIK.Injection.IUbikPlugin
{
}
public class TestPlugin : UBIK.Injection.IUbikPlugin
{
}
Interface: IUbikInjectionMetaData
Managing plugins correctly presumes the following information, as defined by the interface UBIK.Injection.IUbikInjectionMetaData.
[ExportMetadata("ID", "C149402E-BC86-46D6-8D1B-63C86894EA77")]
[ExportMetadata("Type", typeof(TestPlugin))]

[ExportMetadata("Description", "Tests the injection management")]
[ExportMetadata("Version", 1)]
[ExportMetadata("Company", "Augmensys GmbH")]

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 | Integer | 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 |
