Class LanguageCustomizingAnalyzerRegistry

java.lang.Object

org.apache.jackrabbit.core.query.lucene.LanguageCustomizingAnalyzerRegistry

All Implemented Interfaces:

org.apache.jackrabbit.core.query.lucene.AnalyzerRegistry<String>

public class LanguageCustomizingAnalyzerRegistry
extends Object
implements org.apache.jackrabbit.core.query.lucene.AnalyzerRegistry<String>

An implementation of AnalyzerRegistry that associates Analyzers to languages so that a language-specific Analyzer can be used if available.

Note that this AnalyzerRegistry performs partial match on languages so that variants (e.g. en_US) of the same language can use the Analyzer configured for the main variant (e.g. en) automatically. Also note that, when an Analyzer is registered for a specific language with this AnalyzerRegistry, it is automatically wrapped to first check whether a property-specific Analyzer has been configured (in which case it's used) and then filter the token streams using ASCIIFoldingFilter.
