Introduction

Basic Prerequisites

Creating an own plugin requires to add 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
{
}

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("Name", "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
Company	String	Information about the Company (for UI Presentation)
Copyright	String	Copyright Information (for UI Presentation)

Supported Plugin Types
