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:
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".
