The ModelElement type exposes the following members.
| Name | Description | |
|---|---|---|
 | Id | Gets the ID of the element. |
| IsActive | Gets the IsActive flag and verifies to see whether the element is active. |
| IsDeleted | Gets the IsDeleted flag and checks to see whether the element has been deleted from the model. |
| IsDeleting | Gets the IsDeleting flag and verifies whether the element is currently being deleted from the model. |
| Partition | Gets or sets the Partition that contains the element. |
| Store | Gets the Store that contains the element. |
| Name | Description | |
|---|---|---|
| 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. |

| 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. |
| AddExtension<T>(ModelElement) | Extend the specified 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. |
| CanMerge | Verifies whether a source element can be added to this element. |
| ChooseMergeTarget(ElementGroup) | Selects a target element to accept as its child an element that the user wants to copy, drag, or create. |

| Delete(Guid[]) | Deletes an element from the model. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |

| GetExtension(ModelElement, DomainClassInfo) | |
| GetExtension(ModelElement, Guid) | |
| GetExtension(ModelElement, Type) | Get the ExtensionElement of the specified type from the available extensions of the specified ModelElement. If the element has no such extension then an InvalidOperationException will be raised. |

| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetRoleCollection<TCollection, TElement>(Guid) | Gets or creates the linked element collection |
| GetRoleCollection<TCollection, TElement>(ModelElement, Guid) | Gets or creates the linked element collection |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsExtendedBy(ModelElement, DomainClassInfo) | Query whether the specified ModelElement is currently extended by an ExtensionElement of a particular type. |
| IsExtendedBy(ModelElement, Guid) | Query whether the specified ModelElement is currently extended by an ExtensionElement of a particular type. |
| IsExtendedBy(ModelElement, Type) | Query whether the specified ModelElement is currently extended by an ExtensionElement of a particular type. |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| MergeConfigure | Allows the model element to configure itself immediately after the Merge process has related it to the target element. |
| MergeDisconnect | Disconnects a source element from a target element. |
| MergeRelate | Creates a relationship between this target element and the specified source element. |
| OnCopy | Called when this element has been created as a copy of another element. |
| OnDeleted | Called when this element has been deleted from the model. |
| OnDeleting | Called when this element is about to be deleted. |
| OnResurrected | Called when this element has been added back to a model. |
| OnRolePlayerPositionChanged | Called when the position of a role has changed. |
| OnRolePlayerPositionChanging | Called when a role player position is about to change. |
| RemoveExtension(ModelElement, DomainClassInfo) | Remove any extension of the specified ModelElement that is of a particular domain type. |
| RemoveExtension(ModelElement, ExtensionElement) | Remove a specified ExtensionElement from the extensions of the specified ModelElement. |
| RemoveExtension(ModelElement, Guid) | Remove any extension of the specified ModelElement that is of a particular type. |
| RemoveExtension(ModelElement, Type) | Remove any extension of the specified ModelElement that is of a particular type. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |

| TryGetExtension(ModelElement, Guid) | |
| TryGetExtension(ModelElement, Type) | |
| TryGetExtension<T>(ModelElement) | Get the ExtensionElement of the specified type from the available extensions of the specified ModelElement. If the element has no such extension then the result will be null. |
