Example 1 with ParentTypesMatcher

use of org.kie.workbench.common.stunner.core.graph.util.ParentTypesMatcher in project kie-wb-common by kiegroup.

the class ConnectorParentsMatchContainmentHandler method evaluateSingleContainment.

@SuppressWarnings("unchecked")

    final GraphEvaluationState state = context.getState();

    final String connectorId = rule.getId();
    // Walk throw the graph and evaluate connector source and target nodes parent match.
