#with_item_list(hashes) ⇒ Object

Use pre-fetched list of items. Particularly useful when parent’s XML already contains enough information about child entities, hence we can parse them on parent already to reduce API requests. Some examples:

- vApp XML contains all the information about each of its child VMs, so we can pre-fetch `vapp.vms`
- VM XML contains all the information about customization, so we can pre-fecth `vm.guest_customization`
- VM XML contains all the information about disks, so we can pre-fetch `vm.disks`
