## Class TermRangeQueryNodeProcessor

- java.lang.Object
- - org.apache.lucene.queryparser.flexible.core.processors.QueryNodeProcessorImpl
  - - org.apache.lucene.queryparser.flexible.standard.processors.TermRangeQueryNodeProcessor

- All Implemented Interfaces:
    QueryNodeProcessor

      public class TermRangeQueryNodeProcessor
      extends QueryNodeProcessorImpl

  This processors process `TermRangeQueryNode`s. It reads the lower and upper bounds value from the `TermRangeQueryNode` object and try to parse their values using a `DateFormat`. If the values cannot be parsed to a date value, it will only create the `TermRangeQueryNode` using the non-parsed values.
  If a `StandardQueryConfigHandler.ConfigurationKeys.LOCALE` is defined in the `QueryConfigHandler` it will be used to parse the date, otherwise `Locale.getDefault()` will be used.
  If a `StandardQueryConfigHandler.ConfigurationKeys.DATE_RESOLUTION` is defined and the `DateTools.Resolution` is not `null` it will also be used to parse the date value.
  See Also:
    `StandardQueryConfigHandler.ConfigurationKeys.DATE_RESOLUTION`, `StandardQueryConfigHandler.ConfigurationKeys.LOCALE`, `TermRangeQueryNode`

    - #### postProcessNode

          protected QueryNode postProcessNode(QueryNode node)
                                       throws QueryNodeException

      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
      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

          protected List<QueryNode> setChildrenOrder(List<QueryNode> children)
                                              throws QueryNodeException

      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
