Returns an Array of 2 ICENodePortCollection objects. The
first collection contains the exposed ports and the second one the
associated compound node ports also known as proxy ports. The
collections work as a pair, the exposed port at position 0 in the
first collection matches the node port at position 0 in the second
collection, etc.
The exposed ports are the contained nodes ports of a compound node
and act as connection points to outer nodes. These ports can be
either ICENodeInputPort or
ICENodeOutputPort objects.
This property and the AddExposedParamToICECompoundNode
command are typically used in pair for exposing the contained node
ports to other graph nodes.
