Class LuceneQueryEngine.LuceneQueryProcessor

java.lang.Object
  org.modeshape.jcr.query.process.QueryProcessor<LuceneProcessingContext>
      org.modeshape.jcr.query.lucene.LuceneQueryEngine.LuceneQueryProcessor

All Implemented Interfaces:

Processor

Enclosing class:

LuceneQueryEngine

protected static class LuceneQueryEngine.LuceneQueryProcessor
extends QueryProcessor<LuceneProcessingContext>

The QueryProcessor implementation used by this LuceneQueryEngine. It varies from the abstract class only by creating a LuceneQueryEngine.LuceneAccessQuery for each access query, and which is resposible for submitting the access query to Lucene.

Constructor Summary

protected

LuceneQueryEngine.LuceneQueryProcessor(String repositoryName, org.hibernate.search.SearchFactory searchFactory)

Method Summary

protected void	closeProcessingContext(LuceneProcessingContext processingContext) A method that can be overridden to close the supplied processing context.
protected ProcessingComponent	createAccessComponent(QueryCommand originalQuery, QueryContext context, PlanNode accessNode, QueryResults.Columns resultColumns, LuceneProcessingContext processingContext) Create the ProcessingComponent that processes a single PlanNode.Type.ACCESS branch of a query plan.
protected LuceneProcessingContext	createProcessingContext(QueryContext queryContext) A method that can be overridden by subclasses to create a single context object used for all the access queries for a single query.
protected void	initialize(LuceneSchema schema)
protected boolean	supportsPushDownExistConstraints()

Method Detail

initialize

protected void initialize(LuceneSchema schema)

supportsPushDownExistConstraints

protected boolean supportsPushDownExistConstraints()

Specified by:

supportsPushDownExistConstraints in class QueryProcessor<LuceneProcessingContext>

createProcessingContext

protected LuceneProcessingContext createProcessingContext(QueryContext queryContext)

Description copied from class: QueryProcessor

A method that can be overridden by subclasses to create a single context object used for all the access queries for a single query.

Overrides:

createProcessingContext in class QueryProcessor<LuceneProcessingContext>

Parameters:

queryContext - the context in which the query is being executed; never null

Returns:

the processing context object; may be null

closeProcessingContext

protected void closeProcessingContext(LuceneProcessingContext processingContext)

Description copied from class: QueryProcessor

A method that can be overridden to close the supplied processing context. This method will always be called after a call to QueryProcessor.createProcessingContext(QueryContext)

Overrides:

closeProcessingContext in class QueryProcessor<LuceneProcessingContext>

Parameters:

processingContext - the processing context in which the query is being executed; null if QueryProcessor.createProcessingContext(QueryContext) returned null

createAccessComponent

protected ProcessingComponent createAccessComponent(QueryCommand originalQuery,
                                                    QueryContext context,
                                                    PlanNode accessNode,
                                                    QueryResults.Columns resultColumns,
                                                    LuceneProcessingContext processingContext)

Description copied from class: QueryProcessor

Create the ProcessingComponent that processes a single PlanNode.Type.ACCESS branch of a query plan.

Specified by:

createAccessComponent in class QueryProcessor<LuceneProcessingContext>

Parameters:

originalQuery - the original query that is being executed; never null

context - the context in which query is being evaluated; never null

accessNode - the node in the query plan that represents the PlanNode.Type.ACCESS plan; never null

resultColumns - the columns that are to be returned; never null

processingContext - the processing context in which the query is being executed; null if QueryProcessor.createProcessingContext(QueryContext) returned null

Returns:

the processing component; may not be null
