All Implemented Interfaces:

Closeable, AutoCloseable

public final class ScopedAnalyzer
extends AnalyzerWrapper

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