All Implemented Interfaces:

Closeable, AutoCloseable, ScopedAnalyzer

public final class ScopedLuceneAnalyzer
extends org.apache.lucene.analysis.AnalyzerWrapper
implements ScopedAnalyzer

A ScopedLuceneAnalyzer is a wrapper class containing all analyzers for a given class. ScopedLuceneAnalyzer behaves similar to PerFieldAnalyzerWrapper by delegating requests for TokenStreams to the underlying Analyzer depending on the requested field name.
