- - org.apache.lucene.queryParser.standard.processors.NumericRangeQueryNodeProcessor

All Implemented Interfaces:

QueryNodeProcessor
```
public class NumericRangeQueryNodeProcessor
extends QueryNodeProcessorImpl
```
This processor is used to convert ParametricRangeQueryNodes to NumericRangeQueryNodes. It looks for StandardQueryConfigHandler.ConfigurationKeys.NUMERIC_CONFIG set in the FieldConfig of every ParametricRangeQueryNode found. If StandardQueryConfigHandler.ConfigurationKeys.NUMERIC_CONFIG is found, it considers that ParametricRangeQueryNode to be a numeric range query and convert it to NumericRangeQueryNode.

StandardQueryConfigHandler.ConfigurationKeys.NUMERIC_CONFIG, ParametricRangeQueryNode, NumericConfig, NumericRangeQueryNode

    Specified by:
    
    postProcessNode in class QueryNodeProcessorImpl
    
    Parameters:
    
    node - node the query node to be post-processed
    
    Returns:
    
    a query node
    
    Throws:
    
    QueryNodeException - if something goes wrong during the query node processing
  - preProcessNode

protected QueryNode preProcessNode(QueryNode node)
                            throws QueryNodeException
```
    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
    
    Throws:
    
    QueryNodeException - if something goes wrong during the query node processing
  - setChildrenOrder

```
    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
    
    Throws:
    
    QueryNodeException - if something goes wrong during the query node processing
