Parameters
- partition
Type: Microsoft.VisualStudio.Modeling.Partition
The partition where the element link is to be created. Typically the DefaultPartition.
- elementLinkType
Type: System.Type
A non-abstract domain relationship defined in the DSL Definition.
- roleAssignments
Type: array<Microsoft.VisualStudio.Modeling.RoleAssignment[]
An array of relationship role assignments for the new element link.
- propertyAssignments
Type: array<Microsoft.VisualStudio.Modeling.PropertyAssignment[]
If the domain relationship defines properties for its instances, you can assign their values here.
Return Value
Type: Microsoft.VisualStudio.Modeling.ElementLink
The ElementLink created.
Remarks
This method of creating a link is more suitable for generated code than for ordinary programming.
The following examples use the types defined in a DSL generated from the Minimal Language solution template.
Examples
To create a link using this method:
ExampleElement element1, element2;
MyLanguageDomainModel dm = ...;
RoleAssignment sourceRole = new RoleAssignment(ExampleElementReferencesTargets.SourceDomainRoleId, element1);
RoleAssignment targetRole = new RoleAssignment(ExampleElementReferencesTargets.TargetDomainRoleId, element2);
ExampleElementReferencesTargets link1 =
dm.CreateElementLink(dm.Store.DefaultPartition,
typeof(ExampleElementReferencesTargets),
new RoleAssignment[] { sourceRole, targetRole},
null)
as ExampleElementReferencesTargets;
This example creates the same link more directly using the domain relationship:
ExampleElementReferencesTargets link = new
ExampleElementReferencesTargets(element1, element2);
If the domain relationship defines role properties on the classes that it associates, and if you do not want a reference to the link, then you can create the link using the role properties. In the Minimal Language DSL, the ExampleElementReferencesTargets relationship defines role properties Source and Target:
// Creates the link without returning a reference to it:
element1.Targets.Add(element2);
