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 {@link org.apache.lucene.queryParser.core.processors.QueryNodeProcessor}. +

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

+ +

+A pipeline of processors can be assembled using {@link org.apache.lucene.queryParser.core.processors.QueryNodeProcessorPipeline}. +

+ +

+Implementors may want to extend {@link org.apache.lucene.queryParser.core.processors.QueryNodeProcessorImpl}, which simplifies +the implementation, because it walks automatically the {@link org.apache.lucene.queryParser.core.nodes.QueryNode}. See +{@link org.apache.lucene.queryParser.core.processors.QueryNodeProcessorImpl} for more details. +
