Full quote If the properties at the ends of a binding connector are typed by a ValueType, the connector specifies that the instances of the properties shall hold equal values, recursively through any nested properties within the connected properties. Next snippet If the properties at the ends of a binding connector are typed by a Block, the connector specifies that the instances of the properties shall refer to the same block instance. Related snippets A Binding Connector is a connector which specifies that the properties at both ends of the connector have equal values. Related snippets (backlinks) When a proxy port is connected to a single internal part [or port or internal part], the connector shall be a binding connector, or have the same semantics as a binding connector ... (the value of the proxy port and the connected internal part are the same; links of associations typing the connector are between all objects and themselves, and no others) When a proxy port is connected to multiple internal parts, the connectors have the same semantics as a single binding connector to an aggregate of those parts, supporting all their features, and treating flows and invocations from outside the aggregate... This aggregate is not a separate element of the system, and only groups the internal parts for purposes of binding to the proxy port. Internal connectors to proxy ports can be typed by association blocks, including when the connector is binding. Association Visit also Visit also (backlinks) Flags
