Examples with BusinessEntity org.ovirt.engine.core.common.businessentities.BusinessEntity used on opensource projects

Example 1 with BusinessEntity

use of org.ovirt.engine.core.common.businessentities.BusinessEntity in project ovirt-engine by oVirt.

the class BackendAssignedAffinityLabelsResource method add.

@Override
public Response add(AffinityLabel label) {
    validateParameters(label, "id");
    IdQueryParameters parameters = new IdQueryParameters(GuidUtils.asGuid(label.getId()));
    org.ovirt.engine.core.common.businessentities.Label entity = getEntity(org.ovirt.engine.core.common.businessentities.Label.class, QueryType.GetLabelById, parameters, label.getId(), true);
    BusinessEntity<Guid> parent = constructor.create();
    parent.setId(GuidUtils.asGuid(parentId));
    org.ovirt.engine.core.common.businessentities.Label updatedLabel = new LabelBuilder(entity).entity(parent).build();
    // Add the affinity label using the backend "update" operation. As the backend will return the added label as
    // the result of the operation, we can fetch it using a simple "identity" resolver, that just returns the same
    // value it is passed.
    LabelActionParameters updateParams = new LabelActionParameters(updatedLabel);
    return performCreate(ActionType.UpdateLabel, updateParams, (IResolver<Label, Label>) result -> result);
