Query Node Processors

The package org.apache.lucene.queryParser.processors contains interfaces that should be implemented by every query node processor.

The interface that every query node processor should implement is QueryNodeProcessor.

A query node processor should be used to process a QueryNode tree. QueryNode trees can be programmatically created or generated by a text parser. See org.apache.lucene.queryParser.core.parser for more details about text parsers.

A query node processor should be used to process a QueryNode tree. QueryNode trees can be programmatically created or generated by a text parser. See org.apache.lucene.queryParser.core.parser for more details about text parsers.

A pipeline of processors can be assembled using QueryNodeProcessorPipeline.

Implementors may want to extend QueryNodeProcessorImpl, which simplifies the implementation, because it walks automatically the QueryNode. See QueryNodeProcessorImpl for more details.
