Example 1 with ResourceService

use of org.onosproject.net.resource.ResourceService in project onos by opennetworkinglab.

Example 2 with ResourceService

use of org.onosproject.net.resource.ResourceService in project onos by opennetworkinglab.

the class AllocationsCommand method printAllocation.

        print("%s", did);

    } else {
        print("%s%s allocated by %s", Strings.repeat(" ", level), asVerboseString(num), portConsumers);
    }
    // FIXME: This workaround induces a lot of distributed store access.
    // ResourceService should have an API to get all allocations under a parent resource.
