Create UBIK Plugin


UBIK® Plugins are loaded dynamically into the UBIK® Kernel by the UBIK® Injection Management based on the Microsoft Extensibility Framework (MEF).

[edit]

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)

Example

    [Export(typeof(UBIK.Injection.IUbikPlugin))]
    [ExportMetadata("ID", "C149402E-BC86-46D6-8D1B-63C86894EA77")]
    [ExportMetadata("Type", typeof(TestPlugin))]
    [ExportMetadata("Name", "TestPlugin" )]
    [ExportMetadata("Description", "Tests the injection management")]
    [ExportMetadata("Version", 1)]
    [ExportMetadata("MinimumKernelVersion", "2.4.0.0")]
    [ExportMetadata("MinimumDatabaseVersion", "2.4.0.0")]
    [ExportMetadata("Company", "Augmensys GmbH")]
    [ExportMetadata("Copyright", "2014, Augmensys GmbH")]
    public class TestPlugin : UBIK.Injection.IUbikPlugin
