      • traverse

        java.lang.Object traverse​(java.lang.Object node)
        Entry point for the PicoVisitor traversal. The given node is the first object, that is asked for acceptance. Only objects of type PicoContainer, ComponentAdapter, or Parameter are valid.
        Parameters:
        node - the start node of the traversal.
        Returns:
        a visitor-specific value.
        Throws:
        java.lang.IllegalArgumentException - in case of an argument of invalid type.
      • visitContainer

        boolean visitContainer​(PicoContainer pico)
        Visit a PicoContainer that has to accept the visitor.
        Parameters:
        pico - the visited container.
        Returns:
        CONTINUE_TRAVERSAL if the traversal should continue. Any visitor callback that returns ABORT_TRAVERSAL indicates the desire to abort any further traversal.
      • visitComponentAdapter

        void visitComponentAdapter​(ComponentAdapter<?> componentAdapter)
        Visit a ComponentAdapter that has to accept the visitor.
        Parameters:
        componentAdapter - the visited ComponentAdapter.
      • visitComponentFactory

        void visitComponentFactory​(ComponentFactory componentFactory)
        Visit a ComponentAdapter that has to accept the visitor.
        Parameters:
        componentAdapter - the visited ComponentAdapter.
      • visitParameter

        void visitParameter​(Parameter parameter)
        Visit a Parameter that has to accept the visitor.
        Parameters:
        parameter - the visited Parameter.
