Need help finding the function that is being called by a module when a node is saved

Hello,

I am using the geocode module to add geodata to already existing location nodes on our site. To speed up the process of geocoding 3000+ nodes, I have enlisted the help of views bulk operations.

The idea is simple, geocode provides a cck field that can geo data based on a cck address field. All you have to do is edit and save the node and magically that node now has geo coordinates. Since VBO can save batches of nodes out of the box, I thought, that will be perfect, just select all 3000+ nodes and batch save them all in one go.

The problem is, that for some reason performing a bulk "save node" with VBO not only doesn't save the node with the geodata, it actually removes geodata if the node was already geocoded, d-oh!

I posted a support request on the VBO project page explaining my situation, and it was suggested that if I could find the function that does the geocoding when the node is saved, I could use VBO to call that function directly.

Unfortunately, I don't speak module very well, and I am having difficulty finding the function I need... I have looked through the geocode module code for hook_nodeapi, which I understand to be the function that would be called, but cannot find one...

is anyone out there able to take a quick look at the code and suggest some ideas?

here is what the module looks like: http://pastebin.com/XZtpzTgp
and the helper geocode_widget module: http://pastebin.com/cz1YVpsg
and the geocode include file: http://pastebin.com/4bq9m93x

There are a few other include files too, not sure if there is a way to get a all-in-one look at the order in which all includes etc... are called, and then compile that into one big php script to run with VBO?

Any help here would be greatly appreciated...

thanks,
Andy :)
