Class ParserAdaptorInfo

java.lang.Object
  com.esri.gpt.catalog.lucene.ParserAdaptorInfo

public class ParserAdaptorInfo
extends Object

Parser adaptor info.

Stores all the information neccesary to create instance of the parser adaptor. Parser adaptor is a mechanizm to delegate query parsing to another mechanizm.

Adaptor is never accessible directly. Instead, an instance of IParserProxy is created and used to submit query through the adaptor to the external mechanizm.

Adaptor class has to have one mandatory method String parse(String queryTerm), and may have optional method void init(Properties attributes).

Typically, adaptors are defined in Lucene configuration node, which may look like on the example below:

  <lucene
     indexLocation="c:/gpt9/lucene-index/catalog1"
     analyzerClassName="org.apache.lucene.analysis.standard.StandardAnalyzer">
     <adaptor name="ontology" className="com.esri.gpt.catalog.lucene.StandardParserAdaptor">
        <attribute key="baseUrl" value="http://localhost:8080/OntologyService/query?term="/>
     </adaptor>
  </lucene>
