Omit operator port connections (Was: What is one feature you 'd love to see i 2004-08-17 - By Guy Rabiller

Hey Felix,
it depends if you use scripted or compiled operators.
If it is for scripted operators, then as they support run-time creation, you
can use the CustomOperator method "AddPortGroup".
You have the Min and Max arguments, if you set Min=0, then this PortGroup is
optional.
The use the "ConnectToGroup" method.
( check the CustomOperator object in the scripting doc for more details ).
For compiled operators, first you have to add to your spdl, in a Group
section the Min and Max tokens:
Group "Group_2"
{
Origin = Pick;
PickMessage = "Pick CustomPSet";
Input "InPSet"
{
Major = {9E04FCEE-10 (See http://CEE-10.ora-code.com)F3-11D0-943A-00AA006D3165};
Minor = {76332575-D242-11D0-B69C-00AA003B3EA6};
Interface = {00000000-0000-0000-C000-000000000046};
}
Min = 0;
Max = Infinite;
}
Here the PortGroup is optional and accept an infinite number of connections.
Then from C++, to connect items to PortGroups, you also have to use the
"ConnectToGroup" method.
Unfortunately, this method is not exposed to the CPP SDK, so you will have
to use the ComAPIHandler:
// oOp is a CustomOperator
// lGroup the PortGroup index
// oRef the CRef to the item being connected
CValue outArg;
CValueArray args(0);
args.Add( lGroup );
args.Add( oRef );
CComAPIHandler comOp( oOp.GetRef() );
comOp.Invoke( L"ConnectToGroup",CComAPIHandler::Method, outArg, args );
Hope this helps.
