Delegation Connectors (OOM)

Delegation connectors represent the paths of communication by which parts inside a classifier connect to ports on the outside of that classifier and request and provide services to each other.

A delegation connector can be created in the following diagrams:

• Composite Structure Diagram
• Component Diagram

Delegation connectors in a composite structure diagram

In the example below a delegation connector connects the supplier port "sql" on the outside of the class "TitleImp" to the client part "TitleDataAccess" via a port "sql". A second delegation connector connects the supplier part "TitleManager" via the port "mgr" to the port "mgr" on the outside of the class "TitleImp".

Delegation connectors in a component diagram

In the example below a delegation connector connects the supplier part "TitleDataAccess" via the port "sql" to the client port "sql" on the outside of the component "PersistentTitle".
