vCO plugin, which interface corresponds to the action when the "reload" menuitem is clicked for a node in the inventory?

Hi,

     The vCO plugin I'm working on has an inventory implementation, just like the inventory vCenter Server plugin has provided.

My question is that, when the "Reload" button for a node is clicked (like the screenshot shown above) , in the IPluginFactory implementation, which "unique" method will be invoked.

When I say "unique", I mean a method that will only be triggered when "Reload" button is clicked. In this method I'd like to clear the cache and reload the node and its children nodes.

I do know that some methods within IPluginFactory are invoked, for example find(...), findRelation(...), but it doesn't not make sense to clear cache and reload in those methods as they are not unique (meaning that they would be triggered in other places where no clearing cache should be intended).

So please let me know which method is hooked specifically for the "Reload" menuitem, or any other solution to implement what I wanted. Thanks in advance!
