  - ### postProcessNode

    protected QueryNode postProcessNode(QueryNode node)
    Description copied from class: `QueryNodeProcessorImpl`
    This method is invoked for every node when walking up the tree.
    Specified by:
      `postProcessNode` in class `QueryNodeProcessorImpl`
    Parameters:
      `node` - node the query node to be post-processed
    Returns:
      a query node

  - ### preProcessNode

    protected QueryNode preProcessNode(QueryNode node)
    Description copied from class: `QueryNodeProcessorImpl`
    This method is invoked for every node when walking down the tree.
    Specified by:
      `preProcessNode` in class `QueryNodeProcessorImpl`
    Parameters:
      `node` - the query node to be pre-processed
    Returns:
      a query node

  - ### setChildrenOrder

    protected List<QueryNode> setChildrenOrder(List<QueryNode> children)
    Description copied from class: `QueryNodeProcessorImpl`
    This method is invoked for every node that has at least on child. It's invoked right before `QueryNodeProcessorImpl.postProcessNode(QueryNode)` is invoked.
    Specified by:
      `setChildrenOrder` in class `QueryNodeProcessorImpl`
    Parameters:
      `children` - the list containing all current node's children
    Returns:
      a new list containing all children that should be set to the current node
