    // In a graph A -> B -> {C, D}
    // showing that A requires B, and B requires C,D
    // then a depth-first visit would satisfy required ordering, for example a valid depth first visit is also a valid sort here: C, D, B, A.

Example 3 with ItemDefinition

use of org.eclipse.bpmn2.ItemDefinition in project drools by kiegroup.

the class ItemDefinitionDependenciesSorter method dfVisit.

/**
 * Performs a depth first visit, but keeping a separate reference of visited/visiting nodes, _also_ to avoid potential issues of circularities.

    List<ItemDefinition> neighbours = allNodes.stream().filter(// filter out `node`
    n -> !n.getName().equals(node.getName())).filter(// I pick from allNodes, those referenced by this `node`. Only neighbours of `node`, because N is referenced by NODE.
