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

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: IUbikModule

The module must implement the UBIK.Injection.IUbikModule interface and has to be registered for MEF composition by defining the export contract via an attribute.

[Export(typeof(UBIK.Injection.IUbikPlugin))]

public class TestModule : UBIK.Injection.IUbikModule
{
}

Interface: IUbikInjectionMetaData

Managing modules correctly presumes the following information, as defined by the interface UBIK.Injection.IUbikInjectionMetaData.

[ExportMetadata("ID", "C149402E-BC86-46D6-8D1B-63C86894EA77")]
[ExportMetadata("Type", typeof(TestModule))]
[ExportMetadata("Name", "TestModule" )]
[ExportMetadata("Description", "Tests the injection management")]
[ExportMetadata("Version", 1)]
[ExportMetadata("Company", "Augmensys GmbH")]

Mandatory information

Name	Type	Description
ID	String	Unique ID of the module
Type	System.Type	Systemtype of the module; used for filtering the module during loading.

Optional information

Name	Type	Description
Name	String	Name of the module (for UI Presentation)
Description	String	Descrirption of the module (for UI Presentation)
Version	Integer	Version of the module. As there are more modules with the same ID, only the module with the highest Version is available.
TargetApplication	PluginTargetApplication	Possibility to limit the module 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)

To be implemented for IUbikModule

Name	Description
SystemDefinitionsProvider	The instance of the SystemDefinitions for the respective module is provided.
Initialize	Initializes the module.
Initialized	Returns true when the plugin is initialized
Terminate	Terminates the UBIKEnvironment if it has been initialized.
DependencyModules	Returns the module information for which it has a dependency.
