Node Linking API (PyLink class)

This is the class for manipulating links between nodes in the tree as returned by PyNode.getInputLink() and PyNode.getOutputLink().

PyNode getFromNode() - returns the upstream node.

int getFromOutput() - returns which output connection of the upstream node this link connect to.

PyNode getToNode() - returns the downstream node.

int getToInput() - returns which input connection of the downstream node this link connects to.
