Extension Methods
| GetDslDefinitionModelElement(PresentationElement) |
This method ensures that the real model element corresponding to the PresentationElement is returned. For DslDesigner PELs, the corresponding subject may actually be an internal TreeNode class and not the actual MEL. This method handles those cases correctly so that the actual MEL is returned. |
| AddExtension(ModelElement, DomainClassInfo) |
Extend this ModelElement with a newly instantiated extension of the specified domain type. An InvalidOperationException will be thrown if the element already has an extension of that type. |
| AddExtension(ModelElement, ExtensionElement) |
Extend this ModelElement with a specific extension. An InvalidOperationException will be thrown if the element already has an extension of the same type. |
| AddExtension(ModelElement, Guid) |
Extend this ModelElement with newly instantiated extension of the identified domain type. An InvalidOperationException will be thrown if the element already has an extension of that type. |
| AddExtension(ModelElement, Type) |
Extend this ModelElement with a newly instantiated extension of the specified type. An InvalidOperationException will be thrown if the element already has an extension of that type. |
| AddExtension<T>(ModelElement) |
Extend this ModelElement with a newly instantiated extension of a particular type. An InvalidOperationException will be thrown if the element already has an extension of the same type. |
| GetAllExtensions(ModelElement) |
Return an enumerable that performs a breadth first traversal across the tree of extension elements embedded in this ModelElement. |
| GetBaseElement(ModelElement) |
Returns the root of the virtual MEL in which the specified ModelElement is participating. |
| GetExtension(ModelElement, DomainClassInfo) | |
| GetExtension(ModelElement, Guid) | |
| GetExtension(ModelElement, Type) |
Get the ExtensionElement of the specified type from the available extensions of this ModelElement. If the element has no such extension then an InvalidOperationException will be raised. |
| GetExtension<T>(ModelElement) |
Get the ExtensionElement of the specified type from the available extensions of this ModelElement. If the element has no such extension then an InvalidOperationException will be raised. |
| IsExtendedBy(ModelElement, DomainClassInfo) |
Query whether this ModelElement is currently extended by an ExtensionElement of a particular type. |
| IsExtendedBy(ModelElement, Guid) |
Query whether this ModelElement is currently extended by an ExtensionElement of a particular type. |

Remove any extension of the specified ModelElement that is of a particular type. |
| RemoveExtension(ModelElement, Type) |
Remove any extension of this ModelElement that is of a particular type. |
| TryGetExtension(ModelElement, DomainClassInfo) | |
| TryGetExtension(ModelElement, Guid) | |
| TryGetExtension(ModelElement, Type) | |
