QueryNodeProcessorPipeline (Lucene 2.9.4 API)

java.lang.Object
- org.apache.lucene.queryParser.core.processors.QueryNodeProcessorPipeline

All Implemented Interfaces:

QueryNodeProcessor

Direct Known Subclasses:

StandardQueryNodeProcessorPipeline
```
public class QueryNodeProcessorPipeline
extends java.lang.Object
implements QueryNodeProcessor
```
A QueryNodeProcessorPipeline class should be used to build a query node processor pipeline. When a query node tree is processed using this class, it passes the query node tree to each processor on the pipeline and the result from each processor is passed to the next one, always following the order the processors were on the pipeline. When a QueryConfigHandler object is set on a QueryNodeProcessorPipeline, it takes care of also setting this QueryConfigHandler on all processor on pipeline.
