Interface for a node port.
Use this interface to access port metadata and connectivity.
A port represents an input or output slot on a node and users can connect ports to other ports to form graph relationships.
Each port has a unique name within its node context, a data type, and a direction.
Users can only connect a port to another port if they are compatible as follows:
The ports must have opposite PortDirection (i.e., one input and one output).Either both ports must have the same data type or the output port must be a derived data type and the input port, a base data type.
Of course the derived data type must be derived from the same base type.
To retrieve the node that owns the port, use INodeExtensions.GetNode.
