Does this 'link_pre_link_transform' method get called?

See

netlab/netsim/modules/gateway.py

Line 111 in f0d3970

def link_pre_link_transform(self, link: Box, topology: Box) -> None:

Everywhere else (vlan, vrf, dhcp) it's called "link_pre_transform", a 'grep' shows no obvious invocations

[jbemmel]

I guess it does:

netlab/netsim/modules/__init__.py

Line 103 in f0d3970

link_transform("pre_link_transform",topology)

The sequence of hooks called is (hopefully relatively accurately) described here: https://netlab.tools/dev/transform/#global-data-transformation (and subsequent sections).

See also https://netlab.tools/dev/transform/#node-level-module-hooks and https://netlab.tools/dev/transform/#link-level-module-hooks. Those hooks were added to avoid having a "loop over all nodes" or "loop over all links" code all over the place when it's not needed (= when you don't need the global context).

Several modules use the node_something hooks (to process data of a single node), not sure any module uses link_something hook at the moment.
