v3.0
Returns the number of PortGroups
(or -1 if there is a failure). Operators that do not define port
groups, namely ones created in the scripted operator editor or
expressions, report that they have one port group. This is not
strictly correct but allows the user to write generic code for
accessing the ports (see the example for the Operator object.
The PortGroupCollection.Count
property (which can be accessed from Operator.PortGroups) returns 0.
oLong = Operator.GetNumPortGroups(); |
/*
This example illustrates how to generate a mesh by using the loft operator and
a number of input curves. The code also illustrates how to traverse the operator's
port group, port group instances and ports and logs the name of the port, its type
and the full path name of the object connected to the port.
