## Operator.Port

### Description

Finds and returns the specified Port object for the operator. PortGroup and PortGroupInstance (index) arguments are ignored for scripted operators created using the scripted operator editor (also known as runtime scripted operators). For all other types of operators if PortGroup and PortGroupInstance are not specified, the first port found with the given Name is returned.
Note: Python does not support input parameters on properties, so this property will fail in Python. Use the Operator.GetPort2 method instead.

### C# Syntax

    // get accessor
    Port Operator.get_Port( String in_bstrPort, String in_bstrPortGroup, Int32 in_lPortGroupInstance );

### Parameters

Parameter | Type | Description
--- | --- | ---
Name | String | Name of a port
PortGroup | String | Name of a port group. Default Value: "" (empty string)
PortGroupInstance | Long | The port group instance index. This argument does not apply to runtime operators. If you don't provide a port group this argument is ignored. Default Value: 0

### Examples

#### JScript Example

    /*
            The following code illustrates how to get the port from an operator if
            you know its name.
    */
    NewScene( null, false );
    var oObject = ActiveSceneRoot.AddGeometry("Sphere","MeshSurface");
    apply_deform( oObject );
    var oDeformOperator = oObject.ActivePrimitive.ConstructionHistory.Find( "MyDeform" );
    var oPort = oDeformOperator.Port("InGeom","MainGroup",0);
    var oInputGeometry = oPort.Target2;
    Application.LogMessage( oDeformOperator.Name + " is reading from the " + oInputGeometry.FullName );
    function apply_deform( oObject )
    {
            var op = XSIFactory.CreateScriptedOp( "MyDeform", MyDeform_Update.toString(), "JScript" );
            // Define connections
            var group = op.AddPortGroup( "MainGroup" );
            var ioport = op.AddIOPort( oObject.ActivePrimitive, "Geom", group.Index );
            // Define parameters
            var pdef = XSIFactory.CreateParamDef2( "Factor", siDouble, 0.5, 0, 1 );
            op.addparameter(pdef);
            // Connect operator
            op.Connect(oObject);
    }
    function MyDeform_Update( ctx, out, InGeom )
    {
            // Get the factor.
            var dFactor = ctx.Parameters("Factor").Value
            // Get the array of point positions.
            var aPnts = InGeom.Value.Geometry.Points.PositionArray.toArray();
            // Deform geometry
            // Update the object//s point positions.
            out.Value.Geometry.Points.PositionArray = aPnts;
            return;
    }
    //
