Description

ICENodePort is the base class for ICENode ports such as ICENodeInputPort and ICENodeOutputPort. An ICENodePort is a connection point on an ICENode and connects to other ICENodePort objects. ICENodePort may be connected to something or not connected at all. Ports are organized in groups similar to the Softimage operator Ports, where groups are logical groupings of multiple port connections.
