Some valid FullPorts from the outside Source OMG Systems Modeling Language (SysML) 1.6 Copyright information About Object Management Group copyright in text extracts quoted from OMG specifications for educational purposes Snippet kind INFO UML keywords Port SysML keywords FullPort "standard" Port ProxyPort Previous snippet Using existing blocks with ports only requires knowing the port types, because they define the features available for linking or communication with those ports via connectors. Full quote The stereotypes of proxy and full ports might be elided in these cases to simplify diagrams. Next snippet Related snippets SysML identifies two [EDIT:ADDITIONAL] usage patterns for ports, one where ports act as proxies for their owning blocks or its internal parts (proxy ports), and another where ports specify separate elements of the system (full ports). Ports that are not specified as proxy or full are simply called “ports.” Modelers can choose between proxy or full ports at any time in the development lifecycle, or not at all, depending on their methodology. Modelers have the option of applying stereotypes for proxy and full ports to indicate whether ports are specifying features of their owners and internal parts (proxy), or for themselves separately (full). This is a concern when defining ports, rather ... Related snippets (backlinks) Visit also Visit also (backlinks) Flags
