Note how the directed item features of
fuelTankPort are redefined in the binding context to provide "clean" binding targets (as opposed to binding to inherited directed item features):
part tank : FuelTankAssembly {
port redefines fuelTankPort {
out item redefines fuelSupply;
in item redefines fuelReturn;
}
bind fuelTankPort.fuelSupply = pump.pumpOut;
bind fuelTankPort.fuelReturn = tank.fuelIn;
}In any case, if you wish to benefit from the Webel "Trust the Type" i/o recipe, if you do redefine a port, parameter, or directed feature you should also include the Type of the redefined port, parameter, or directed feature (and even if that's also tedious and a bit WET) so that the concise and legible Webel "Trust the Type" display modes work.
