|
|
* We assume that the DataTypes are ordered from the most likely to the
|
|
* least likely when iterating or comparing them with "<".

* C) If no port is connected, the same logic can be applied with all ports
|
|
* instead of connected ones. TODO: Try other ideas, for instance look at
|
|
* the last plugin output when |for_input| is false (note: when StrictIO

* the outs of the last plugin should be the same as the outs of the route
