| Parameter | Description |
|---|---|
| value | When successful, contains the value assigned to the port’s field. |
bool
true if the port is not connected and a field value is available; otherwise, false.
Tries to retrieve the current value assigned to the port’s UI field.
This method is intended for editor-time inspection of an input port’s value, configured through a field
displayed in the UI. If the port is connected, the field is hidden and no value is available, so the method returns false.
If the value was never explicitly set, this method still returns true, and will contain the default
value for type T.
