Class QueryNodeProcessorPipeline

public class QueryNodeProcessorPipeline
extends Object
implements QueryNodeProcessor, List<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 also takes care of setting this QueryConfigHandler on all processor on pipeline.


Constructor Summary
QueryNodeProcessorPipeline()
          Constructs an empty query node processor pipeline.
QueryNodeProcessorPipeline(QueryConfigHandler queryConfigHandler)
          Constructs with a QueryConfigHandler object.
