com.exalead.search.queryprocessing.StandardQueryRunner

All Implemented Interfaces:

QueryProcessingRunner

Direct Known Subclasses:

MultiQueryRunner

public class StandardQueryRunner
extends java.lang.Object
implements QueryProcessingRunner

Method Detail

handleQuery

public void handleQuery(QueryContext context)
                 throws QueryProcessingException

Specified by:

handleQuery in interface QueryProcessingRunner

Throws:

QueryProcessingException

handleProgressiveQuery

public void handleProgressiveQuery(QueryContext context)
                            throws com.exalead.expand.progressive.ProgressiveExpandException

Specified by:

handleProgressiveQuery in interface QueryProcessingRunner

Throws:

com.exalead.expand.progressive.ProgressiveExpandException

protected static void checkQueryNonEmpty(Query query)
                                  throws QueryProcessingException

Throws:

QueryProcessingException

handleUQLQuery

protected Node handleUQLQuery(QueryContext context,
                              java.lang.String queryName,
                              java.lang.String uqlQuery)
                       throws QueryProcessingException

Throws:

QueryProcessingException

setupDefaultPrefix

public void setupDefaultPrefix(java.lang.String defaultPrefix)

handleUserQueryString

protected Node handleUserQueryString(QueryContext context,
                                     java.lang.String queryName)
                              throws QueryProcessingException

Throws:

QueryProcessingException

protected void prettyPrint(QueryContext qc,
                           java.lang.String name,
                           Node qn)

onInit

public void onInit(SearchLogic logic)
            throws java.lang.Exception

Description copied from interface: QueryProcessingRunner

Called when this instance of the runner is created

Specified by:

onInit in interface QueryProcessingRunner

Parameters:

logic - The logic on which this runner will work

Throws:

java.lang.Exception

onDeinit

public void onDeinit(boolean allInstances)
              throws java.lang.Exception

Description copied from interface: QueryProcessingRunner

Called when this instance of the runner is deinitialized. This instance will not be reused after this. Cleanup of instance resources should be done here rather than in a finalizer, as it offers a better control on the resource lifecycle.

Specified by:

onDeinit in interface QueryProcessingRunner

Parameters:

allInstances - Hint indicating whether all instances of the processor are going to be deinitialized, or only this one.

Throws:

java.lang.Exception
