)

public delegate ModelElement^ SourceRolePlayerMapFunction(

JScript does not support delegates.

Parameters

• input
  Type: Microsoft.VisualStudio.Modeling.ModelElement

  The model element that is the original role player in the new link.

Return Value

Type: Microsoft.VisualStudio.Modeling.ModelElement
The model element to use as the new role player in the new link.

Remarks

For a domain class that plays a role in a domain relationship, the RolePlayerPropertyDescriptor.MapSourceRolePlayer property enables the domain class to insert one model element in place of another when a new link is created.

For example, this delegate is used by the DSL Tools to link the underlying model elements when you link two diagram elements. For more information about how to map diagram elements to model elements, see Mapping Shapes and Connectors.
