PortAt (Operator) *

Introduced

3.0

Description

Returns the specified Port object.

Note: Regardless of the order that ports are added to a Group, input ports are always indexed before output ports. For example, if a custom operator is built with two output ports A and B and two input ports C and D then port 0 will be C, port 1 will be D, port 2 will be A and port 3 will be B.

Scripting Syntax

Operator.PortAt( PortIndex, PortGroupIndex, PortGroupInstance )

C# Syntax

Port Operator.PortAt( Int32 in_lPortIndex, Int32 in_lPortGroupIndex, Int32 in_lPortGroupInstance );

Parameters

Return Value

Port

Examples

JScript Example

/*
   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.
