AddExtension(ModelElement, DomainClassInfo)

Extend the specified ModelElement with a newly instantiated extension of the specified domain type. An InvalidOperationException will be thrown if the element already has an extension of the same type.

public:
 static Microsoft::VisualStudio::Modeling::ExtensionElement ^ AddExtension(Microsoft::VisualStudio::Modeling::ModelElement ^ element, Microsoft::VisualStudio::Modeling::DomainClassInfo ^ extensionClass);

public static Microsoft.VisualStudio.Modeling.ExtensionElement AddExtension (Microsoft.VisualStudio.Modeling.ModelElement element, Microsoft.VisualStudio.Modeling.DomainClassInfo extensionClass);

static member AddExtension : Microsoft.VisualStudio.Modeling.ModelElement * Microsoft.VisualStudio.Modeling.DomainClassInfo -> Microsoft.VisualStudio.Modeling.ExtensionElement

Public Shared Function AddExtension (element As ModelElement, extensionClass As DomainClassInfo) As ExtensionElement

Parameters

element: ModelElement

ModelElement to be extended

extensionClass: DomainClassInfo

The domain class of the type of ExtensionElement to be added

Returns

ExtensionElement

The newly instantiated and added extension

Applies to

AddExtension(ModelElement, ExtensionElement)

Extend the specified ModelElement with a specified extension. An InvalidOperationException will be thrown if the element already has an extension of the same type.

public:
 static Microsoft::VisualStudio::Modeling::ExtensionElement ^ AddExtension(Microsoft::VisualStudio::Modeling::ModelElement ^ element, Microsoft::VisualStudio::Modeling::ExtensionElement ^ extension);

public static Microsoft.VisualStudio.Modeling.ExtensionElement AddExtension (Microsoft.VisualStudio.Modeling.ModelElement element, Microsoft.VisualStudio.Modeling.ExtensionElement extension);

static member AddExtension : Microsoft.VisualStudio.Modeling.ModelElement * Microsoft.VisualStudio.Modeling.ExtensionElement -> Microsoft.VisualStudio.Modeling.ExtensionElement

Public Shared Function AddExtension (element As ModelElement, extension As ExtensionElement) As ExtensionElement

Parameters

element: ModelElement

ModelElement to be extended

extension: ExtensionElement

The ExtensionElement to be added

Returns

ExtensionElement

The added extension

Remarks

Although attempts to add a duplicate extension type are caught here, there are other cases where extensions may clash by contributing duplicate properties or roles, for example when two extensions are added that inherit from a common base that defines IMS properties and/or roles. Such cases are detected by IMergeElements implementation on ModelElement, but not by this low-level API

Applies to

AddExtension(ModelElement, Guid)

Extend the specified ModelElement with a newly instantiated extension of the identified domain type. An InvalidOperationException will be thrown if the element already has an extension of the same type.

public:
 static Microsoft::VisualStudio::Modeling::ExtensionElement ^ AddExtension(Microsoft::VisualStudio::Modeling::ModelElement ^ element, Guid extensionClassId);

public static Microsoft.VisualStudio.Modeling.ExtensionElement AddExtension (Microsoft.VisualStudio.Modeling.ModelElement element, Guid extensionClassId);

static member AddExtension : Microsoft.VisualStudio.Modeling.ModelElement * Guid -> Microsoft.VisualStudio.Modeling.ExtensionElement

Public Shared Function AddExtension (element As ModelElement, extensionClassId As Guid) As ExtensionElement

Parameters

element: ModelElement

ModelElement to be extended

extensionClassId: Guid

The domain class id of the type of ExtensionElement to be added

Returns

ExtensionElement

The newly instantiated and added extension

Applies to

AddExtension(ModelElement, Type)

Extend the specified ModelElement with a newly instantiated extension of the specified type. An InvalidOperationException will be thrown if the element already has an extension of the same type.

public:
 static Microsoft::VisualStudio::Modeling::ExtensionElement ^ AddExtension(Microsoft::VisualStudio::Modeling::ModelElement ^ element, Type ^ extensionType);

public static Microsoft.VisualStudio.Modeling.ExtensionElement AddExtension (Microsoft.VisualStudio.Modeling.ModelElement element, Type extensionType);
