- Classes in org.apache.lucene.queryParser.core.processors used by org.apache.lucene.queryParser.core.processors
  Class and Description
  QueryNodeProcessor A `QueryNodeProcessor` is an interface for classes that process a `QueryNode` tree.
  QueryNodeProcessorImpl This is a default implementation for the `QueryNodeProcessor` interface, it's an abstract class, so it should be extended by classes that want to process a `QueryNode` tree.
