Full quote Proxy ports are always typed by interface blocks, a specialized kind of block that has no behaviors or internal parts. Next snippet Full ports cannot be behavioral in the UML sense of standing in for the owning object, because they handle features themselves, rather than exposing features of their owners, or internal parts of their owners. 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). Related snippets (backlinks) Proxy ports identify features of the owning block or its internal parts that are available to external blocks through external connectors to the ports. They do not specify a separate element of the system from the owning block or internal parts. ProxyPort::2_interfaceblock Proxy ports shall only be typed by interface blocks. Proxy ports do not specify their own behaviors or internal parts, and shall be typed by interface blocks. Their nested ports shall also be proxy ports. Visit also Visit also (backlinks) Flags
