Class ClassifierQueryParser

java.lang.Object
  com.raritantechnologies.concept.classifier.ClassifierQueryParser

All Implemented Interfaces:

IConfigurable, IQueryParser

public class ClassifierQueryParser

extends java.lang.Object

implements IQueryParser

Uses a DocumentClassifier to parse a query to determine if the query matches one or more of the Document matchers. If so, the name of the document matcher is added to the query.

This can be used to develop an Inference-driven search application. If the documents are tagged by a unique identifier based on the DocumentMatcher ID, this ID can be used to find tagged documents at search time if the query is determined to be a match.

OrderedMap	parse(OrderedMap params, ILoginInfo userInfo)
OrderedMap	parse(OrderedMap params, java.lang.String language, ILoginInfo userInfo) Translate using the input parameters if this is how the query is passed.
void	setLanguage(java.lang.String language)
void	setSessionID(java.lang.String id) Allows QueryParser object to access the sessionData.

getErrors

public java.util.List getErrors()

Description copied from interface: IQueryParser

Returns the errors that occurred during the translate() step.

Specified by:

getErrors in interface IQueryParser

Returns:

the list of error(s) (if any) that occurred.

setSessionID

public void setSessionID(java.lang.String id)

Description copied from interface: IQueryParser

Allows QueryParser object to access the sessionData.

Specified by:

initialize

public void initialize(org.w3c.dom.Element elem)

Description copied from interface: IConfigurable

Initializes the object from an XML tag or element. This method is called by the Framework as part of the application initializtion. see ConfigurationManager, XMLConfigurationManager, XMLSearchFieldMapFactory, XMLSearchSourceFactory. Configurable objects that are owned or contained by other configurable objects will be initialized in by the parent object.

Specified by:
