Examples with LinksTreeNode org.ovirt.engine.api.restapi.resource.utils.LinksTreeNode used on opensource projects

Example 1 with LinksTreeNode

use of org.ovirt.engine.api.restapi.resource.utils.LinksTreeNode in project ovirt-engine by oVirt.

the class BaseBackendResource method follow.

/**
 * Follows links in the entity according to value of "follow" URL query parameter.
 * A valid value of'follow' is a comma separated list of strings, which represent
 * internal links to be followed. Links may have several 'levels' denoted by periods.
 * e.g: GET ...api/vms?follow="nics,disk_attachments.template,disk_attachments.disks"
