oh right, you want 'ConnectedPorts' and 'ConnectedNodes' property of an
ICENodePort class. this example isn't a proper step through the graph but
it shows you what you want... i think :)
from siutils import si
si = si() # win32com.client.Dispatch('XSI.Application')
from siutils import log # LogMessage
from siutils import disp # win32com.client.Dispatch
from siutils import C # win32com.client.constants
for op in si.Selection(0).ActivePrimitive.ConstructionHistory:
if op.Type == "ICETree":
ICETree = op
# output port direction
log("output ports")
for node in op.Nodes:
for port in node.OutputPorts:
for connectedPort,connectedNode in zip(port.ConnectedPorts,
port.ConnectedNodes):
log("%s.%s -> %s.%s" % (node.Name, port.Name,
connectedNode.Name, connectedPort.Name))
# input port direction
log("input ports")
for node in op.Nodes:
for port in node.InputPorts:
for connectedPort,connectedNode in zip(port.ConnectedPorts,
port.ConnectedNodes):
log("%s.%s -> %s.%s" % (node.Name, port.Name,
connectedNode.Name, connectedPort.Name))
