Examples of org.picocontainer.PicoVisitor.traverse()

org.picocontainer.PicoVisitor.traverse()
Entry point for the PicoVisitor traversal. The given node is the first object, that is asked for acceptance. Only objects of type {@link PicoContainer}, {@link ComponentAdapter}, or {@link Parameter} are valid. @param node the start node of the traversal. @return a visitor-specific value. @throws IllegalArgumentException in case of an argument of invalid type. @since 1.1

        List visitedList = new LinkedList();
        PicoVisitor visitor = new RecordingStrategyVisitor(visitedList);
        visitor.traverse(parent);
        assertEquals(expectedList, visitedList);
    }
