PortReference class sealed
A Reference to a port on a BridgeModule.
This abstract class provides a unified interface for accessing and manipulating ports on a BridgeModule, including support for port slicing, connections, and hierarchical port punching operations.

other. -
getsLogic(
Logic other) → void - Connects this port to be driven by a Logic signal.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
