## Method Details

### 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
