Examples with LinkDescription org.onosproject.net.link.LinkDescription used on opensource projects

Example 1 with LinkDescription

use of org.onosproject.net.link.LinkDescription in project onos by opennetworkinglab.

the class SimpleLinkStore method composeLink.

// Guarded by linkDescs value (=locking each Link)
private Link composeLink(Map<ProviderId, LinkDescription> descs) {
    ProviderId primary = getBaseProviderId(descs);
    LinkDescription base = descs.get(verifyNotNull(primary));
    ConnectPoint src = base.src();
    ConnectPoint dst = base.dst();
    Type type = base.type();
    DefaultAnnotations annotations = DefaultAnnotations.builder().build();
    annotations = merge(annotations, base.annotations());
    for (Entry<ProviderId, LinkDescription> e : descs.entrySet()) {
        if (primary.equals(e.getKey())) {
            continue;
        }
        // TODO: should keep track of Description timestamp
        // and only merge conflicting keys when timestamp is newer
        // Currently assuming there will never be a key conflict between
        // providers
        // annotation merging. not so efficient, should revisit later
        annotations = merge(annotations, e.getValue().annotations());
    }
    boolean isDurable = Objects.equals(annotations.value(AnnotationKeys.DURABLE), "true");
    return DefaultLink.builder().providerId(primary).src(src).dst(dst).type(type).state(ACTIVE).isExpected(isDurable).annotations(annotations).build();
}
