Constructor Detail

JsonAnalyzer

public JsonAnalyzer(org.apache.lucene.util.Version version,
            org.apache.lucene.analysis.Analyzer fieldAnalyzer,
            org.apache.lucene.analysis.Analyzer valueAnalyzer)

Create a JsonAnalyzer with the specified Analyzers for field names and values.

The default analyzer for field names will be associated with the datatype JSONDatatype.JSON_FIELD. The default analyzer for values will be associated with the datatype XSDDatatype.XSD_STRING.

Parameters:

fieldAnalyzer - Default Analyzer for the field names

valueAnalyzer - Default Analyzer for the values

Method Detail

setValueAnalyzer

public void setValueAnalyzer(org.apache.lucene.analysis.Analyzer analyzer)

setFieldAnalyzer

public void setFieldAnalyzer(org.apache.lucene.analysis.Analyzer analyzer)

registerDatatype

public void registerDatatype(char[] datatype,
                    org.apache.lucene.analysis.Analyzer a)

Assign an Analyzer to be used with that key. That analyzer is used to process tokens generated by the JsonTokenizer.

Parameters:

datatype - The datatype key

a - the associated Analyzer

clearDatatypes

public void clearDatatypes()

Remove all registered Datatype Analyzers.
