Listing down inventory items

Can anyone point me to sample code on how to call Inventory service for given plugin?

I have following but I would like to go to specific plugin and go to specific workflow output and list down all inventory items in that.

    private VcoSession session;

inventoryService = new InventoryService(session);

        System.out.println(inventoryService.getInventoryRoot().getHref());

This gets me to root but I dont see anything to drill down to specific plugin form here. Do I need to loop through all links to get to specific link/plugin? or Am I missing something here?

Any pointers will be helpful. Some sample code to have a look will be great.

TIA
