Class AnalysisRegistry

java.lang.Object

org.elasticsearch.index.analysis.AnalysisRegistry

All Implemented Interfaces:

Closeable, AutoCloseable

public final class AnalysisRegistry
extends Object
implements Closeable

An internal registry for tokenizer, token filter, char filter and analyzer. This class exists per node and allows to create per-index IndexAnalyzers via build(IndexSettings)
