All Implemented Interfaces:

LuceneSearchMapperRegistry

public class CacheBackedLuceneSearchMapperRegistry
extends java.lang.Object
implements LuceneSearchMapperRegistry

A search mapper registry that operates on a cache only. The purpose of this cache is to minimise lookups against the plugin subsystem. If a mapper cannot be found in the cache, this registry currently does not fall back to looking it up in the actual plugin subsystem.

This cache is initialised on the very first search mapper lookup and is only updated in response to a plugin event (see LuceneSearchMapperRegistryCacheUpdateListener).
