Examples with BaseResource org.ovirt.engine.api.model.BaseResource used on opensource projects

Example 1 with BaseResource

use of org.ovirt.engine.api.model.BaseResource in project ovirt-engine by oVirt.

the class LinkFollower method fetchData.

/**
 * For the provided collection-type entity (e.g: Nics), follow the link represented by the
 * provided node. Do not follow child-links of this node.
 *
 * For example, for a Nics object:
 *
 *   nics [nic1, nic2]
 *
 * and the tree:
 *
 *   vnicprofiles
 *        networkfilter
 *        qos
 *
 * This method fetches all vnicprofiles of nic1, nic2, and sets them in these Nic objects.
 * The method will return the fetched vnic-profile objects. The child links networkfilter, qos
 * are purposely ignored.
