Example 11 with GraphProvider

use of org.opennms.features.topology.api.topo.GraphProvider in project opennms by OpenNMS.

the class DefaultTopologyService method getPreferredLayoutAlgorithm.

// Determines default layout
@Override
public LayoutAlgorithm getPreferredLayoutAlgorithm(String metaTopologyId, String namespace) {
    Objects.requireNonNull(metaTopologyId);
    Objects.requireNonNull(namespace);
    final GraphProvider graphProvider = getGraphProvider(metaTopologyId, namespace);
    final String preferredLayout = graphProvider.getDefaults().getPreferredLayout();
